Ultrafast programmable Bragg reflection in photonic integrated circuits

Yunxiang Song, Pawan Ratra, Danxian Liu +12

The paper demonstrates programmable distributed Bragg reflectors on a photonic chip by using electro‑optic control of ferroelectric domains in thin‑film lithium niobate waveguides,…
