摘要
A VCSEL includes a substrate, and an epitaxial VSCEL structure on the substrate. The epitaxial VSCEL structure includes a resonant cavity, including a gain region, disposed between a first reflector and a partially reflecting second reflector. At least one of the first or second reflectors includes a first sub-wavelength grating to provide spectral control for optical emission from the VCSEL. The first sub-wavelength grating can be operable to lock a wavelength of an optical beam for emission from the VCSEL substantially to a wavelength defined by the grating.
