英文摘要	A VCSEL (100) having a metallic heat spreading layer (128) adjacent a semiconductor buffer layer (122) containing an insulating structure (124). The heat spreading layer (128) includes an opening (130) that enables light emitted by an active region (120) to reflect from a distributed Bragg reflector (DBR) top mirror (132) located above the heat spreading layer (128). A substrate (112) is below the active region (120). A lower contact (114) provides electrical current to that substrate (112). The lower contact (114) includes an opening (115) that enables light emitted from the active region (120) to reflect from a distributed Bragg reflector (DBR) lower mirror (116). Beneficially, the substrate (112) includes a slot that enables light to pass through an opening in the lower contact (114). That slot acts as an alignment structure that enables optical alignment of an external feature to the VCSEL (100).
