Photonic Signal Processing: Ultrafast, Broadband, and Quantum

Photonic Signal Processing: Ultrafast, Broadband, and Quantum

Abstract 

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 wave mixing in chip-scale microresonators, and 

(3) demonstration of two- and three-dimensional frequency-bin entanglement of biphoton frequency combs generated via spontaneous four wave mixing from on-chip microresonators.
