All‐Optically Driven Optofluidic Light Modulator
Advanced Optical Materials, EarlyView.In this work, an all‐optically driven optofluidic light modulator is developed, based on the optical actuation of waveguided beams by liquid crystals confined in a microfluidic channel. The photovoltaic effect in lithium niobate is employed to control the alignment of the liquid crystal in the microfluidic channel underneath by a light‐induced electric

Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz
Advanced Photonics Research, EarlyView.This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with
