Giant backward Brillouin interaction in generic InP integrated photonics

Riley te Morsche, Lukas Puts, Weiming Yao +1

We report the first measurement of backward stimulated Brillouin scattering (SBS) in generic InP waveguides, supporting enhanced Brillouin gain of $g_B/Q_m = 3.5 \pm 0.6~\text{W}^{…
