Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes
Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.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

Optical Durability of Contemporary PV Encapsulants Through Artificial UV Weathering
Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1189-1199, September 2026.Encapsulant choice can be used to mitigate UV‐induced degradation in modern silicon photovoltaic modules, but this strategy is only effective if encapsulants are durable under UV weathering. This study identifies optical changes to 14 commercial encapsulants as a function of UV weathering and identifies that, while changes to material transmittance ...
