Ultralow Dissipation Mechanical Resonators for Quantum Optomechanics, Nils

Johan Engelsen1, Sergey A. Fedorov1, Amir H. Ghadimi1, Mohammad J. Bereyhi1, Alberto Beccari1, Ryan Schilling1, Dalziel J. Wilson2, Tobias J. Kippenberg1; 1Ecole Polytechnique

Fédérale de Lausanne, Switzerland; 2IBM Research — Zürich, Switzerland. We dem-

onstrate dissipation dilution engineering techniques for ultralow dissipation mechanical resonators. The Si3N4 nanobeams show quality factors (Q) as high as 800 million and Q×f exceeding 1015 Hz—both records at room temperature.

Spin-Preserving Chiral Photonic Crystal

Mirror, Behrooz Semnani1,2, Jeremy Flannery2, Zhenghao Ding2, Rubayet Al Maruf2,

Brightness Theorems for Nanophoton-

ics, Hanwen Zhang1, Chia Wei Hsu1, Owen Miller1; 1Yale Univ., USA. We present nanophotonic ‘’brightness theorems’’, a set of power-concentration bounds that generalize their ray-optical counterparts, and motivate the concept of ‘’ wave étendue’’. We show their ramifications in the design of metasurfaces and waveguide combiners.

Solving Hard Computational Problems with Coupled Lasers, Nir Davidson1; 1Weizmann

Inst. of Science, Israel. We present a new a

new system of coupled lasers in a modified degenerate cavity that is used to solve difficult computational tasks.

Michal Bajcsy2,1 1ECE, Univ. of Waterloo,

;

Canada; 2Inst. for Quantum Computing,

Canada. We report on experimental realization of a chiral photonic-crystal structure which exhibits extreme intrinsic chira-optical activity. Formation of quasi-bound-statesin-continuum allows selective reflection of the circular polarization states of light and unconventionally preserves the handedness.

Dynamical gauge fields for phonons in an optomechanical system, Javier Del Pino1,

John P. Mathew1, Ewold Verhagen1; 1AMOLF, Netherlands. We demonstrate a synthetic gauge field for phonon transport in a nanooptomechanical platform. Employing timemodulated radiation pressure forces, we evidence nonreciprocal nanomechanical phase transfer. We show how this enables new classes of phononic topological insulators.

Lossless Zero-Index Guided Modes via Bound States in the Continuum, Momchil

Minkov1, Ian Williamson1, Meng Xiao1, Shan-

hui Fan1; 1Stanford Univ., USA. Zero-index

metamaterials are sought for a number of applications, but have thus far always been associated with significant optical loss. We overcome this shortcoming by designing non-radiative zero-index modes in an alldielectric photonic crystal slab.

The Meaning and Use of Phase in Subwavelength Scattering, Zhean Shen1,

Aristide Dogariu1; 1Univ. of Central Florida,

CREOL, USA. We show that the influence of evanescent wave is preserved in the phase of far field as an energetic time delay during scattering. We demonstrate the capability for sub-wavelength sensing by far-field phase measurements.

By

ultrafast heterodyne measurements of light transport dynamics in a silicon waveguide lattice, we experimentally demonstrated the existence of a zero-energy mode whose topological characteristics are enhanced by non-Hermitian quantum phase engineering.

Power–Bandwidth Limits in Near-Field

Nanophotonics, Owen Miller1, Hyungki Shim1; 1Yale Univ., USA. We find upper bounds to near-field optical response, for any material over any bandwidth. We apply this approach to CDOS, a photon-entanglement measure, and derive the first general bounds to near-field radiative heat transfer.

Mode-Dependent Coupling and Vectorial Optical Vortices in Metallic Nanolaser

Arrays, Midya Parto1, William Hayenga1, Demetrios N. Christodoulides1, Mercedeh

Khajavikhan1; 1Univ. of Central Florida,

CREOL, USA. We demonstrate both theoretically and experimentally that metallic nanolasers display different coupling behaviors depending on the vectorial electromagnetic modes within each nanocavity. Symmetric, antisymmetric, as well as vector-vortex lasing supermodes are observed in such structures.

Albert Schliesser1,2 1Niels Bohr Inst., Den-

;

mark; 2Niels Bohr Inst., Center for Hybrid Quantum Networks (Hy-Q), Denmark. We

measure mechanical displacements within 35% of the Heisenberg limit. By exploiting quantum correlations in an optomechanical system, we achieve for the first time a total sensitivity below the standard quantum limit by 1.5 dB.

As the demands of performance and integration level keep increasing, the design and optimization of nanophotonic devices become computationally expensive and time-inefficient. Advanced computational methods and artificial intelligence, especially its subfield of machine learning, have led to revolutionary development in many applications, such as web searches, computer vision, and speech/image recognition. The complex models and algorithms help to exploit the enormous parameter space in a highly efficient way. In this review, we summarize the recent advances on the emerging field where nanophotonics and machine learning blend. We provide an overview of different computational methods, with the focus on deep learning, for the nanophotonic inverse design. The implementation of deep neural networks with photonic platforms is also discussed. This review aims at sketching an illustration of the nanophotonic design with machine learning and giving a perspective on the future tasks. Keywords: deep learning; (nano)photonic neural networks; inverse design; optimization. 1. Introduction Nanophotonics studies light and its interactions with matters at the nanoscale [1]. Over the past decades, it has received rapidly growing interest and become an active research field that involves both fundamental studies and numerous applications [2,3].

A profound understanding of the underlying physics has inspired the emergence of a new frontier of materials and devices in the past few decades. is thesis explores the concepts and approaches for manipulating light at the wavelength-scale in a variety of topics, including anti-reective coatings, on- chip silicon photonics, optical microcavities and nanolasers, microwave particle accelerators, and optical nonlinearities. In Chapter , an optimal tapered prole that maximizes light transmission be- tween two media with different refractive indices is derived from analytical theory and numerical modeling. A broadband wide-angle anti-reective coating at the air/silicon interface is designed for the application of photovoltaics.

Stinaff The use of metal droplet epitaxy may provide a novel method of growing laterally coupled nanostructures. We will present optical studies of InAs/GaAs nanostructures which result in twin quantum dots (QD) formed on a single quantum ring (QR). Previous studies have investigated the coupling between vertically grown quantum dot pairs. In this thesis, we have used photoluminescence (PL) and photoluminescence excitation (PLE) to examine the possibility of energy transfer and coupling between quantum dot pairs in a single InGaAs quantum ring grown by droplet epitaxy. Power dependent photoluminescence spectra reveal a few peaks at low power, which are identified with emission from the ground state of the individual dots. As the power is increased we observe multi-exciton and excited state emission. We then perform PLE, tuning the excitation laser energy continuously from the high energy ring emission down to the individual dot states.

    A solution-processed 1.53 μm quantum dot laser with temperature-invariant emission wavelength S. Hoogland, V. Sukhovatkin, I. Howard, S. Cauchi, L. Levina, E. H. Sargent The Edward S. Rogers Sr. Department of Electrical and Computer Engineering University of Toronto Toronto, ON, Canada, M5S 3G4 [email protected]; [email protected] Abstract: Sources of coherent, monochromatic short-wavelength infrared (1-2 μm) light are essential in telecommunications, biomedical diagnosis, and optical sensing. Today’s semiconductor lasers are made by epitaxial growth on a lattice-matched single-crystal substrate. This strategy is incompatible with direct growth on silicon. Colloidal quantum dots synthesized in solution can, in contrast, be coated onto any surface. Here we show a 1.53 μm laser fabricated using a remarkably simple process: dipping a glass capillary into a colloidal suspension of semiconductor quantum dots. We developed the procedures to produce a smooth, low-scattering-loss film inside the capillary, resulting in a whispering gallery mode laser with a well-defined threshold. While there exist three prior reports of optical gain in infrared-emitting colloidal quantum dots [1, 2, 3], this work represents the first report of an infrared laser made using solution processing. We also report dλmax/dT, the temperature-sensitivity of lasing wavelength, of 0.03 nm/K, the lowest ever reported in a colloidal quantum dot system and 10 times lower than in traditional semiconductor quantum wells. ©2006 Optical Society of America OCIS codes: (140.5960) Semiconductor lasers; (160.3380) Laser materials; (999.999) Nanocrystal quantum dots.
