Electrically Tunable On‐Chip Topological Photonics with Integrated Carbon Nanotubes
Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.This work demonstrates electrically tunable on‐chip topological THz devices by integrating 2D carbon nanotube (CNT) sheets with valley‐Hall photonic crystals, enabling broadband transmission modulation (71% modulation depth) and tunable narrowband filtering (0.54 GHz shift) through electrically induced thermal tuning. This advancement paves the way for

Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities
Advanced Materials, Volume 38, Issue 13, 3 March 2026.A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.

Advanced Optical Materials, Volume 14, Issue 10, 13 March 2026.An optimized RF‐sputtering process is developed for the deposition of n‐doped germanium thin films exhibiting strongly enhanced THz emission under fs‐laser excitation. By tuning deposition temperature and thickness, highly (111)‐oriented films with an effective bandgap of ∼0.77 eV and improved optoelectronic properties are achieved, leading to a ∼35 ...
