Nonlinear Optical Processes for Spectral Broadening and Short Pulse Generation Hongyu Hu University of Connecticut, [email protected]
University of Connecticut OpenCommons@UConn Doctoral Dissertations University of Connecticut Graduate School 1-13-2017 Nonlinear Optical Processes for Spectral Broadening and Short Pulse Generation Hongyu Hu University of Connecticut, [email protected] Follow this and additional works at: https://opencommons.uconn.edu/dissertations Recommended Citation Hu, Hongyu, "Nonlinear Optical Processes for Spectral Broadening and Short Pulse Generation" (2017). Doctoral Dissertations. 1353. https://opencommons.uconn.edu/dissertations/1353 Nonlinear Optical Processes for Spectral Broadening and Short Pulse Generation Hongyu Hu, PhD University of Connecticut, 2017 The dramatic progress in optical communication is attributed to the development of wavelength- division multiplexing and time-division multiplexing technologies, which employ broadband light source and ultrashort optical pulses respectively to carry signals in optical fibers. Supercontinuum generation is the spectral broadening of narrow-band incident pulses by the propagation through optical waveguides made of nonlinear materials. In this PhD dissertation, I show the design of a tapered lead-silicate optical fiber for supercontinuum generation. The physical mechanisms of optical pulse evolution are explained, which involve various nonlinear optical effects including self-phase and cross-phase modulation, stimulated Raman scattering, four-wave mixing, modulation instability and optical soliton dynamics. I have also proposed planar waveguides with longitudinally varying structure to manage chromatic dispersion, and numerically simulated the generation of (1) broadband and (2) flat octave-spanning supercontinuum output. The coherence property and noise sensitivity of supercontinuum are also investigated in this dissertation, which depend strongly on pumping conditions. A hybrid mode- locked erbium-doped fiber ring laser, which combines rational harmonic active mode-locking technique and graphene saturable absorber, has been designed and experimentally demonstrated to produce optical pulse train. -

Note Silicon Saxony Day 2010
AMBASSADE DE FRANCE EN ALLEMAGNE SERVICE POUR LA SCIENCE ET LA TECHNOLOGIE Berlin, le 20 mai 2010 Rapprochement entre Dresde et Grenoble lors du salon Silicon Saxony Day 2010: 1. La région de la Saxe La Saxe (Sachsen), est le Länder le plus peuplé de l'Allemagne de l'Est et le 6 ème au niveau fédéral. Il a une frontière commune avec la Pologne et la République tchèque. Les villes les plus importantes sont Dresde et Leipzig avec environ 515.000 habitants. En 2007, son PIB de 93 milliards d’euros représente 3,8% de celui du pays, tandis que son PIB/habitants de 22,1 k€ le place en dessous de la moyenne nationale (29 k€) et de l’ensemble des régions françaises, bien que ce soit la meilleure performance pour les Länder de l’Est (hors Berlin). L'économie saxonne s’appuie sur les secteurs traditionnels comme les mines, le bâtiment, l’automobile, mais aussi sur des technologies de pointe comme la microélectronique, l'énergie et les biotechnologies . Le tissu industriel se compose d’environ 150.000 entreprises en majorité des PME. 0,1% des entreprises ont plus de 500 employés et réalisent plus de 50 millions d’euros de chiffre d’affaires. En 2008, le secteur des hautes technologies emploie 55 % des salariés de la Saxe. Dans la branche des nanotechnologies, 80 entreprises (sur 500 pour l’ensemble de l’Allemagne) sont implantées à Dresde et sa région, ainsi que 40 centres de recherche spécialisés dans ce domaine. En plus de ses quatre Universités Techniques (Dresde, Chemnitz, Freiberg et Leipzig) comptant plus de 75.000 étudiants, la Saxe comporte plus de 50 instituts de recherche extra-universitaires. -
