Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes
Laser &Photonics Reviews, EarlyView.This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip
