Abstract

The aim of this work is to enhance the Q value of a photonic crystal microring resonator that can be used to buffer optical signals (in a pulse train). A conventional photonic crystal microring resonator having 60° bends exhibits poor confinement of light due to the radiation losses at the bending points. Hence, we replaced conventional bent waveguides with circularly curved ones. The Q value of the resulting ring resonator is measured, and we demonstrate, as an example, an eightfold enhancement of the Q value at a wavelength of 1340 nm. Finally, we also estimate the Q value of a ring waveguide that excludes the optical coupling between the input/output waveguides, showing that the replacement of a sharply bent waveguide by a curved one increases the Q value by up to 5.2 times at a wavelength of 1340 nm.
