WAVELENGTH DIVISION MULTIPLEXED ARRAY OF LONG-WAVELENGTH VERTICAL CAVITY LASERS

摘要

A semiconductor device includes an array of long-wavelength VCSELs pumped by a short-wavelength optical pump. The array of long-wavelength VCSELs includes a series of semiconductor recesses, where each semiconductor recess is between two layers of a VCSEL, substantially overlapping the transverse model profile of the VCSEL under operation.
