Coherent Antiguided High Contrast Grating VCSEL Array
2022 28th International Semiconductor Laser Conference (ISLC)(2022)
Abstract
We demonstrate coherent VCSEL arrays using a novel antiguided high contrast grating (HCG) structure that consists of two distinct HCG dimensions in one monolithic layer. Narrow single-lobed fundamental and double-lobed highest-order array mode emission are achieved with in- and out-of- phase coupling sections, respectively.
