Abstract:
There is provided a semi-circular resonator using a whispering gallery mode (WGM) and an optical sensor using the same. Accordingly, an active region that is a waveguide of an active layer in which laser oscillation is caused by gains of advancing beams is deeply etched in a semi-circular or semi-ring shape.
