Abstract

The temperature tuning of microcavity ring and disk resonators with wide free spectral range Δλfsr and high finesse is demonstrated. AlGaAs and GaAs ring and disk resonators with diameters of 10.5 and 20.5 μm evanescently coupled to single-mode waveguides are fabricated. Strong lateral waveguide confinement allows micron-size cavities with negligible bending loss and the resonators can be fabricated with reasonably low loss using nanofabrication techniques resulting in a high finesse. The 10.5 μm disk resonator yields a finesse as high as 120 and Δλfsr of 21.6 nm. The temperature tuning is 1.3 nm/10 °C suitable for a thermally-controlled switch or widely tunable filter.
