Photoluminescence from a VCSEL structure a-SiN/sub x/:H microcavity

Summary form only given. Microcavity effects on the photoluminescence (PL) of porous Si has already been reported. Recently, we have observed visible and near infrared (IR) PL from hydrogenated amorphous Si nitride (a-SiN/sub x/:H) grown by low temperature PECVD. We have also reported the enhancement and inhibition of PL in an a-SiN/sub x/:H microcavity formed with metallic mirrors. The a-SiN/sub x/:H used in the microcavity was grown both with and without NH/sub 3/. For the Si rich a-SiN/sub x/:H grown without NH/sub 3/, the PL is in the red-near IR. For the N rich a-SiN/sub x/:H grown with NH/sub 3/, the PL is in the blue-green. In this paper, we report on the bright and spectrally pure PL of a-SiN/sub x/:H in a VCSEL structure microcavity.
