Robust characterization of photonic integrated circuits
Jiajia Wang, Xingyuan Xu, Haoran Zhang +4
Photonic integrated circuits (PICs) offer ultra-broad optical bandwidths that enable unprecedented data throughputs for signal processing applications. Dynamic reconfigurability en…
Phase retrieval of programmable photonic integrated circuits based on an on-chip fractional-delay reference path
Xingyuan Xu, Guanghui Ren, Aditya Dubey +5
Programmable photonic integrated circuits (PICs), offering diverse signal processing functions within a single chip, are promising solutions for applications ranging from optical c…
Optical Adaptive LMS Equalizer with an Opto-electronic Feedback Loop
Xumeng Liu, Xingyuan Xu, Arthur James Lowery
We propose a photonic adaptive Least-Mean-Squares equalizer with an opto-electronic feedback loop to determine the updating of an optical Finite-Impulse-Response filter's weights,…
Highly tunable broadband RF photonic fractional Hilbert transformer based on a Kerr soliton crystal microcomb source
Mengxi Tan, Xingyuan Xu, David J. Moss
We demonstrate an RF photonic fractional Hilbert transformer based on an integrated Kerr micro-comb source featuring a record low free spectral range of 48.9 GHz, yielding 75 micro…
Cyclic spectra for wavelength-routed optical networks
Bill Corcoran, Zihan Geng, Valery Rozental +1
We propose occupying guard-bands in closely-spaced WDM systems with redundant signal spectral components, to increase tolerance to frequency misalignment and channel shaping from m…
Enhanced asymmetrically-clipped optical OFDM
Arthur James Lowery
Asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) is a technique that sacrifices spectral efficiency in order to transmit an orthogonally frequen…
