Claim Text:
1. A VCSEL comprising: a bottom electrode; a bottom mirror stack electrically coupled to and over the bottom electrode; an active region having a lasing region over the bottom mirror stack; a top mirror stack over the active region; an oxide aperture over the active region; a contact region over the top mirror stack; a contact electrode electrically coupled with the contact region; a graphene intra-cavity absorber having at least one graphene region and at least one dielectric region adjacent to the graphene region and between the graphene region and lasing region such that the dielectric region isolates the graphene region from the lasing region, the graphene intra-cavity absorber including a bottom graphene region over the contact region, a dielectric region over the contact region, and a top graphene region over the dielectric region; a graphene electrode electronically coupled with the top graphene region; and a dielectric mirror over the graphene region.
