As a fundamental optical approach to interferometry, Sagnac interference has been widely
used for reflection manipulation, precision measurements, and spectral engineering in …

Discrete frequency modes, or bins, present a blend of opportunities and challenges for
photonic quantum information processing. Frequency-bin-encoded photons are readily …

Micro-combs-optical frequency combs generated by integrated micro-cavity resonators–offer
the full potential of their bulk counterparts, but in an integrated footprint. They have enabled …

We report a broadband radio frequency (RF) channelizer with up to 92 channels using a
coherent microcomb source. A soliton crystal microcomb, generated by a 49 GHz micro-ring …

We review recent work on broadband RF channelizers based on integrated optical
frequency Kerr micro-combs combined with passive micro-ring resonator filters, with …

We review recent work on narrowband orthogonally polarized optical RF single sideband
generators as well as dual-channel equalization, both based on high-Q integrated ring …

The quest towards the integration of ultra-fast, high-precision optical clocks is reflected in the
large number of high-impact papers on the topic published in the last few years. This interest …

Over the past decade, optical frequency combs generated by high-Q microresonators, or
optical microcombs, which feature compact device footprints, low power consumption, and …

We report a dual-polarization radio frequency (RF) channelizer based on microcombs. Two
high-Q micro-ring resonators (MRRs) with slightly different free spectral ranges (FSRs) are …

We theoretically investigate advanced multi-functional integrated photonic filters formed by
three waveguide coupled Sagnac loop reflectors (3WC-SLRs). By tailoring the coherent …
