ABSTRACT:
A monolithic array of two or more independently addressable, closely spaced diode lasers having low thermal, electrical, and optical crosstalk. An isolation groove is formed between the adjacent laser elements, which are defined by rib loaded waveguides created by etching mesas above a planar active multilayer waveguide. Separate electrical connections to the ribs, and a common electrical connection to the substrate, enable individual addressing of each laser element. Selectively added blocking layers and/or insulating layers are added to the structure to provide improved electrical and/or thermal isolation.
