(a) The layout of the racetrack resonator and the photodetectors. (b) A top view SEM micrograph of
two racetrack resonator lasers. The racetrack resonator lasers on the top and
bottom have radii of 200 and 100 μm, respectively. (c) The LI curve for a laser
with a bend radius, , of 200 μm, and directional
coupler coupling length, , of 400 μm for various
temperatures. (d) The spectrum for a laser with
= 100 μm and = 400 μm.
