چکیده
A GaInAsP photonic crystal slab microlaser with an integrated passive waveguide was fabricated by a MOCVD butt-joint regrowth process. The boundary between the active and passive regions was optimized for high light transmission. In addition, the edge of the waveguide was designed to output a narrow beam, and the light detection was improved. Consequently, a maximum output power of 0.17 mW was obtained with a differential quantum efficiency of 20%, which would increase to more than 40% under ideal detection conditions.

We present the design, theory and experimental implementation of a low modal volume microlaser based on a line-defect 2D-photonic crystal waveguide. The lateral confinement of low-group velocity modes is controlled by the post-processing of 1 to 3microm wide PMMA strips on top of two dimensional photonic crystal waveguides. Modal volume around 1.3 (lambda/n)(3) can be achieved using this scheme...
