Patent ID: 8848757

Claim:
A high frequency VCSEL array device, comprising: two or more VCSEL devices sharing a common electrical contact and connected in parallel, each VCSEL device among the two or more VCSEL devices forming a first mesa on the common electrical contact, each first mesa including a dielectric layer positioned on a sidewall of each first mesa and in contact with the common electrical contact, a first mirror, a first metal contact, and an active region positioned between the first metal contact and the first minor, the active region being in electrical contact with the first metal contact and generating a light reflected between the first mirror and a second mirror; a ground plane partially surrounding the two or more VCSEL devices; an electrical waveguide; one or more raised areas including a second metal contact electrically connected to the common electrical contact and to the electrical waveguide; and a metal structure deposited over one or more of the two or more VCSEL devices, electrically connected to the first metal contact, electrically isolated from the common electrical contact, and in contact with the electrical waveguide.
