Abstract

A novel enhanced radiation-loss (ERL)-based radial waveguide coupling mechanism for microresonator lasers is experimentally demonstrated for the first time, to the best of our knowledge, resulting in single-directional output from the lasers. A $20\mathrm{\mu m}$ diameter InGaAsP/InP electrically pumped microresonator laser in the form of a microcylinder resonator integrated with a transparent ERL radial output coupler is designed and fabricated. Measurement shows a low $1.5\mathrm{mA}$ lasing threshold and a relatively high output power of $>0.4\mathrm{mW}$.
