A method of manufacturing an optical component for use as a ring resonator comprising an optical fiber formed of a closed ring and two or more gates for resonating or modulating light output

摘要

In the method of manufacturing an optical component for use as the ring resonator according to the present invention, a ring-shaped optical fiber is provided, and the coupler is manufactured by fusion of the optical fiber and tapered shape at the intersection. At least 20 dB of attenuation is introduced into the ring during manufacture of the coupler, and this attenuation is removed again after completion of the coupler.
