Abstract
A new integrated optical ring resonator using a four-port nonsymmetric Mach-Zehnder interferometer as an input/output coupler is demonstrated. The device is fabricated in glass substrate by the double-ion-exchange process. A finesse of 5 at λ = 1.523 μm is measured. Propagation losses of 0.17 dB/cm in the ring waveguide are estimated.Keywords
