    摘要: VCSEL for high speed operation and method of fabrication including a substrate element, a first stack of distributed Bragg reflectors disposed on a surface of the substrate element, an active region lattice matched to a surface of the first stack of distributed Bragg reflectors, and a second stack of distributed Bragg reflectors lattice matched to a surface of the active region. The active region includes a plurality of quantum well layers, or structures, and a plurality of doped barrier layers. The doping of the barrier layers allows for a faster recombination time of the carriers prior to any occurrence of lateral carrier diffusion. This faster recombination time of the carriers prevents turn-off tails when the VCSEL device is switched off.

    摘要: An extended VCSEL structure formed of a first DBR mirror, an active region, a second DBR mirror as partial reflector, and an extended cavity provided by a transparent conductive substrate wafer fused onto the second DBR mirror. The transparent conductive substrate also serves as a convex mirror with a highly reflective dielectric coating to complete the extended cavity VCSEL structure. The use of the extended cavity makes high power single mode operation achievable because an extended cavity introduces high modal loss to the high order laser modes while supporting the lowest order single mode. The large active area allows high output power from the VCSEL.
