Abstract:
A structure for an array of laser diodes comprising:a first metallization layer comprising type one metal contacts; a second metallization layer comprising at least one type two metal contact; a plurality of active regions for generating light of a predetermined frequency disposed below said first metallization layer, each active region in said plurality of active regions electrically coupled to a corresponding type one metal contact in said first metallization layer; first and second waveguide structures that include, respectively, first and second ones of the active regions; each of the first and second waveguide structures further including laser mirror elements; the first waveguide structure having a first lateral surface, the second waveguide structure having a second lateral surface disposed toward and separated from the first lateral surface; an isolation layer of dielectric material over the first and second lateral surfaces, the dielectric material preventing optical coupling at each of the first and second lateral surfaces; a lateral contact layer that couples at least two active regions in the plurality of active regions for generating light to the at least one type two metal contact in the second metallization layer, the at least two active regions having the same thickness for generating light at the same predetermined frequency; and an insulating substrate supporting said plurality of active regions, said first and second waveguide structures, said isolation layer, said lateral contact layer, said first metallization layer and said second metallization layer.
