52. An electrically pumped room temperature continuous-wave (RTCW) vertical cavity laser (VCL) having an optical cavity and emitting at an emission wavelength, said VCL comprising a plurality of layers, a multi-layer first mirror, a multi-layer second mirror, a gain region which comprises at least one gain type from the group consisting of a type I GaSb-based multi-quantum well, type I GaSb-based cascaded quantum wells, a type II GaSb-based multi-quantum well, and a type II InP-based multi-quantum well, said VCL further comprising a first n-type charge injection contact, a second n-type charge injection contact, and a refractive index waveguide comprising an inner region of a higher distributed refractive index and an outer region of lower distributed refractive index, wherein said higher distributed refractive index exceeds said lower distributed refractive index by less than about 0.12.
