Claim 14:
15. An emitter array, comprising:
a first set of emitters; and
a second set of emitters;
wherein the first set of emitters and the second set of emitters are interleaved with each other to form a two-dimensional regular pattern of emitters that emits a random pattern of light; and
wherein the second set of emitters includes at least one degraded emitter, the at least one degraded emitter comprising one or more of:
a central current blocking implant, having an implant width less than a width of an active region of the degraded emitter, positioned substantially centrally with respect to a current confinement aperture of the degraded emitter,
an etched surface extending around dielectric via openings of the degraded emitter and to a depth approximately at a top surface of a top mirror of the degraded emitter,
or
a reduced via, etched through a dielectric passivation/mirror layer of the degraded emitter to expose a metal layer, the reduced via having a reduced size relative to other vias of the emitters in the first set of emitters.
