Two-dimensional optical ring resonators based on radial Bragg resonance

Jacob Scheuer, Amnon Yariv

Research output: Contribution to journalArticlepeer-review


A Bragg-reflection-based ring resonator is proposed and analyzed. Closed-form expressions for the field and dispersion curves for radial Bragg gratings and photonic bandgap crystals are derived. The required gratings exhibit a chirped period and a varying index profile. Small bending radii and strong control over the resonator dispersion are possible by the Bragg confinement. Large free spectral range and low radiation loss are predicted theoretically.
