Exploring the Potential of Microwave Annealing for Enhancing Si‐based GeSn Lasers
Advanced Materials Technologies, EarlyView.We explore low‐thermal‐budget microwave annealing to enhance the performance of group‐IV GeSn lasers on Si. Microwave annealing under optimal conditions can simultaneously relax unwanted compressive strain and enhance the material quality of the GeSn active layer, thereby reducing the threshold and increasing the laser operating temperature.

Novel microwave integrated lowpass filters
Electronics Letters, 1979 The procedure is described for synthesising Cauer Chebyshev lowpass filters of the third order as rectangular microwave integrated structures. The synthesis procedure is based on a two-mode approximation and leads to structures with very small dimensions compared with the usual realisations of such type of filters.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
