Optical frequency combs have been a proven technology in many applications such as frequency spectroscopy, optical atomic clocks and high-speed optical interconnects among others.

Murat Yessenov Propagation-invariant space-time wave packets localized in all dimensions Optical wave packets that are localized in space and time, but nevertheless overcome diffraction and travel rigidly in free space, are a long sought-after field structure with applications ranging from microscopy and remote sensing to nonlinear and quantum optics. However, synthesizing such wave packets requires…

Ricardo Bustos Ramirez Chip-scale optical to RF link via harmonic injection locking Due to their highly stable timing characteristics, optical frequency combs have become instrumental in applications ranging from spectroscopy to ultra-wideband optical interconnects, high-speed signal processing, and exoplanet search. Furthermore, optical frequency combs serve as the main gear to create the most precise time-keeping…

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…
