Lasers capable of generating picosecond and femtosecond pulses of light are now firmly established and widely deployed. Going beyond simple pulse generation, the programmable shaping of ultrafast laser fields into arbitrary waveforms has resulted in substantial impact, both enabling new ultrafast science and contributing to applications in high-speed signal transmission. This seminar introduces recent research in the Purdue University Ultrafast Optics and Fiber Communications Laboratory drawing on ultrafast pulse shaping approaches for photonic signal processing. Time permitting, the following topics will be discussed: (1) ultrabroadband photonics-enabled radio-frequency (RF) signal processing; (2) broadband optical frequency comb fields generated via nonlinear mixing in chip-scale microresonators; (3).applications in quantum photonics, including demonstration of frequency-bin entanglement of photon pairs.

Biography

Andrew Weiner, the Scifres Family Distinguished Professor of Electrical and Computer Engineering at Purdue University, is best known for pioneering work on programmable femtosecond pulse shaping and ultrafast signal processing. His recent work centers on microsonator frequency combs and quantum photonics. Weiner is a member of the National Academy of Engineering and National Academy of Inventors, was selected as a Department of Defense National Security Science and Engineering Faculty Fellow, and has received numerous awards, including the OSA Wood Prize and the IEEE Photonics Society Quantum Electronics Award. He is author of the textbook Ultrafast Optics and recently concluded a six year term as Editor-in-Chief of Optics Express.
