Breaking Reciprocity in Integrated Photonic Devices Through Dynamic Modulation

2020 · arXiv (Cornell University)

Nonreciprocal components, such as isolators and circulators, are crucial components for photonic systems. In this article we review theoretical and experimental progress towards developing nonreciprocal photonic devices based on dynamic modulation. Particularly, we focus on …

Photonic arbitrary linear transformations in the frequency synthetic dimension

2021 · Conference on Lasers and Electro-Optics

Arbitrary linear transformations are central to photonic quantum information processing and machine learning. We present a photonic architecture of time-modulated micro-ring resonators with tunable couplings between frequency modes to achieve arbitrary frequency-dimension linear transformations.
