Claim 0:
1. A VCSEL device comprising:
a substrate;
a laser cavity over the substrate, the laser cavity including a gain section disposed between first and second reflectors, wherein the VCSEL device is operable to emit light through a first end of the VCSEL device, the first end being closer to the first reflector than the second reflector;
an anode surface mount contact; and
a cathode surface mount contact,
wherein each of the anode and cathode surface mount contacts is disposed at a second end of the VCSEL device opposite the first end of the VCSEL device, the VCSEL device further including:
a first electrical connection at the first end of the VCSEL device, wherein the first electrical connection is routed to the anode surface mount contact by way of an opening through the substrate; and
a second electrical connection at a surface of the second reflector, wherein the second electrical connection is either routed to the cathode surface mount contact by way of a same opening through the substrate as the first electrical connection is routed to the anode surface mount contact or by way of direct contact with the substrate.
