ABSTRACT:
An article and method for making a vertical cavity surface emitting laser (101) is provided. The vertical cavity surface emitting laser includes a semiconductor substrate (102) having a first surface (105) on which a first set of distributed Bragg reflectors (103) are deposited. The distributed Bragg reflectors (103) are made of alternating layers of indium aluminum gallium phosphide and aluminum arsenide. An active region (106) is disposed on the distributed Bragg reflectors with a subsequent of and active region (106) and another cladding region (107). Another distributed Bragg reflector (103) is deposited on cladding region (107).
