BIOGRAPHY

III-V / Silicon Photonic Integration [BPN578]
Many semiconductor-based nanolaser cavities using metal have been remarkably reported in past few years. However, the efficient coupling of these small cavities to waveguides still remains a large challenge. Here, we show highly efficient coupling of a wavelength-scale III-V metal-clad high-quality nanolaser cavity operating the fundamental dielectric cavity-mode to a silicon-on-insulator waveguide. By engineering the effective refractive-index and the field distribution of the cavity mode, the quality factor is maximized as 1700 with a modal volume of 0.28 (lambda/n)^3. Furthermore, the coupling efficiency to the waveguide has the potential to be > 80 %.
