Integrated broadband optical isolator via dynamic rotating destructive interference
Kyunghun Han, Yiliang Bao, Junyeob Song +7
Photonic integrated circuits route and shape light on a chip, but back-reflections feed back into coherent on-chip lasers, destabilizing operation and corrupting signals. Robust op…
