In this article, we report the demonstration of directly modulated grating-assisted microcylinder surface-emitting lasers (GAMSELs) with low threshold. Two second-order gratings are added onto the …
High performance InP-based polarization beam splitters (PBSs) with a symmetrical Mach-Zehnder interferometer (MZI) are theoretically and experimentally demonstrated. The p-i-n waveguide is exploite…
