An array of light emitters includes a plurality of light emitting structures formed over a layered structure with at least one quantum well layer. At least one cladding layer is formed on over the at least one quantum well layer. At least one waveguide layer is formed on or over the at least one cladding layer. At least one isolation region is formed at least in between at least two of the plurality of light emitting structures. The at least one isolation region isolates the at least two light emitting structures from each other.
