Strong reflections in the measurement range do of ultra low reflectivity features. Strong reflections in the not affect peaks from weaker reflections. measurement range can cause laser phase noise, which can obscure weaker reflections. EXAMPLE EXAMPLE 56Gbps QSFP+ (Silicon Photonics Integrated Circuit) Single Stage Isolator (Input) OCDR-1000 OFDR-1000 OCDR-1000 OFDR-1000 -95 dB -95 dB Device with some higher reflectivity features- both devices detect the more Device with weak reflections- OFDR is able to detect some lower prominent features, but the OCDR clearly detects some lower reflectivity reflectivity features not evident in the OCDR plot. peaks that are hidden by phase noise in the OFDR plot. 909.590.5473 [email protected] www.generalphotonics.com December 2018 Vol. 32, No. 6 www.PhotonicsSociety.org Terahertz and Millimeter Wave Imaging Vis THz (a) (b) Also Inside: • Nobel Prize in Physics Spotlight • Graduate Student Fellow - A Catch-Up • IEEE Photonics Society Awards and Recognition December 2018 Volume 32, Number 6 FEATURE Research Highlights . 4 – Terahertz and Millimeter Wave Imaging: A Portable Tool for Characterization 13 Lab Tricks . .10 • QAMPy, a DSP Chain for Optical Communication Signals News . .13 • Appointment of New Executive Director of the IEEE Photonics Society • Toshio Fukuda is 2019 IEEE President-elect • President Jim Jefferies on Stepping Ahead and Envisioning the Future • IEEE Photonics Members Honored with 2018 Nobel Prize in Physics • Graduate Student Fellows—A Catch-Up, Part 2 • New Community Formed on Ethics in Autonomous and Intelligent Systems • White House Outlines Quantum Computing Strategy • National Photonics Initiative Praises Bipartisan Approval of NQI Act in U.S. House of Representatives Careers and Awards . .21 • 31st IEEE Photonics Conference Awards and Recognition • IEEE Photonics Annual Chapter Award Winners Announced • Call for Nominations-2019 Distinguished Lecturer Membership Spotlights . .30 • Finisar Team Honored with Australian Prime Minister’s Prize for Innovation 21 Membership. .32 • The 2018 Nobel Prize in Physics of Ashkin, Strickland and Mourou: Intimate portraits of the Nobelists and Their discoveries • SBFoton: Inaugural Optics and Photonics Conference in Brazil Co-organized by IEEE Photonics Society • Live Tutorial for IEEE Africa Stakeholders a Great Success • Diversity Oversight Committee Established to Broaden Community and Ensure Inclusion is Addressed in the Field • Takian Fakhrul: Paving “One-way Streets” for Light Inside Photonic Devices • IEEE Photonics Fund Supporting AAS Scholarships in Support of Workforce Development in Puerto Rico • One Year After Hurricane Maria, a Research Institute in Puerto Rico Struggles to Come Back • IEEE Future Directions Symposium Uses Cross-Organization Collaboration to Extend Attendance and Increase IEEE Membership 30 • IEEE Nominate a Senior Member Initiative Publications . .44 – JLT: CFP Ultra-Wideband WDW Systems – JSTQE: CFP Semiconductor Lasers – JSTQE: CFP Photonics for Deep Learning and Neural Computing – JSTQE: CFP Emerging Applications of Multimode, Multicore and Specialty Fibers – JSTQE: CFP Programmable Photonics – JSTQE: CFP Photonics for Synthetic Dimensions and Topological Insulators COLUMNS Editor’s Column ......... 2 President’s Column .......... 3 December 2018 IEEE PHOTONICS SOCIETY NEWSLETTER 1 Editor’s IEEE Photonics Society Column NICOLAS FONTAINE President Associate Editor of Central, Latin and Chennupati Jagadish South American 2018 has been a great year for photonics.
