Hybrid vertical cavity laser for photonic integrated circuit
Abstract:
According to example embodiments, a hybrid vertical cavity laser for a photonic integrated circuit (PIC) includes: a grating mirror between first and second low refractive index layers, an optical waveguide optically coupled to one side of the grating mirror, a III-V semiconductor layer including an active layer on an upper one of the first and second low refractive index layers, and a top mirror on the III-V semiconductor layer. The grating mirror includes a plurality of bar-shaped low refractive index material portions arranged parallel to each other. The low refractive index material portions include a plurality of first portions having a first width and a plurality of second portions having second width in a width direction. The first and second widths are different.
