The CREOL Student of the Year Award is a program to recognize the outstanding academic, scientific and professional achievements of graduate students in CREOL. Fan Wu Optical thermodynamic theory of nonlinear highly multimoded systems The complex nonlinear behaviors of heavily multimode lightwave structures have been recently the focus of considerable attention. The convoluted spatial-temporal interaction […]

Jose Rafael Guzman-Sepulveda Optical monitoring of blood coagulability during cardiovascular surgery via coherence-gated DLS Light scattering-based approaches have proved robust for monitoring the structural dynamics of complex media thanks to their capability to retrieve collective dynamic information through the intensity fluctuations of the light scattered. In my talk I will address the specific features of […]

Alex Sincore 2 µm Fiber Lasers: Power scaling concepts and challenges Fiber lasers have experienced explosive growth in the past decades, with 1 µm Ytterbium- doped lasers holding >13 % of the laser market. Fiber lasers operating at longer wavelengths, specifically 2 µm Thulium-doped lasers, are experiencing a similar growth in system performance. However, the […]

Hossein Hodaei Novel photonic resonant arrangements using non-Hermitian Exceptional Points In recent years, non-Hermitian degeneracies, also known as exceptional points (EPs), have emerged as a new paradigm for engineering the response of optical systems. Among many different non-conservative photonic configurations, parity-time (PT) symmetric arrangements are of particular interest since they provide an excellent platform to […]

Cheonha Jeon Fundamental Studies of Ultrashort Laser Pulse Interaction with Aerosols Delivering high intensity ultrashort laser pulses over long distances to irradiate targets has gained interest for various applications since the discovery of a laser filament. Laser filamentation in air produces a cylindrically symmetric self-channeled high intensity beam (~ 5 x 1013 W/cm2) generated by […]

Jeffrey Chiles Hybrid Integrated Photonic Platforms and Devices The field of integrated optics has seen vast growth since its beginnings decades ago. The promise of mass-manufacturable, compact, and reliable systems has driven much of this growth.  The use of silicon as an optical platform has been established for several decades, the silicon-on-insulator (SOI) platform being […]

Clémence Jollivet Specialty Fibers for Novel Fiber Lasers and Devices Designs of novel specialty fibers are finely tuned to enable transmission of light carrying specific properties (wavelength, profile, polarization, dispersion, etc.), opening the route towards potential applications such as average or peak power scaling of fiber laser, beam shaping, optical sensing, and  telecommunications. As the […]

Neng Bai Mode-division multiplexed optical communication in few-mode fibers As a promising candidate to break the single-mode fiber capacity limit, mode-division multiplexing (MDM) explores the spatial dimension to increase transmission capacity in fiber-optic communication. Two linear impairments, namely loss and multimode interference, present fundamental challenges to implement MDM. This talk will describe methods to resolve […]

Nazanin Hoghooghi Linear modulation, direct demodulation and channel filtering using injection-locked semiconductor lasers A novel linear interferometric intensity modulator based on an injection-locked laser as an arcsine phase modulator, is described. Spur-free dynamic range of ~130 dB.Hz2/3 is achieved in an analog link employing this modulator. Also, direct demodulation and channel filtering of phase-modulated optical signals […]
