Inhomogeneous waveguides with corrugations have the potential to increase the fundamental mode brightness of edge-emitting lasers as compared to straight waveguides. The corrugations partly suppress the high-order lateral modes of the lasers. The impact of the shape and size of rectangular and triangular types of corrugations on the lasing performance is compared for the first time, and an optimized design is presented.

Copper iodide (CuI) thin films were grown on Si(100) substrates using a copper film iodination reaction method. It was found that γ-CuI films have a uniform and dense microstructure with (111)-orientation. Transmission spectra indicated that CuI thin films have an average transmittance of about 60% in the visible range and the optical band gap is 3.
