III-V photonic crystal lasers heterogeneously bonded to silicon-on-insulator waveguides

We report on the fabrication of InP-based 2D photonic crystal lasers operating around lambda = 1.55 mu m at room temperature, integrated with and evanescently coupled to Silicon-On-Insulator waveguides. Pulsed laser operation is obtained from a line defect photonic crystal waveguide accurately aligned (< 30 nm) on top the SOI circuitry. This active-passive integration is demonstrated using an adhesive bonding technique. Lasing action is demonstrated for several low group velocity modes of the photonic crystal defect waveguide
