We report the measurement of cavity propagation losses in nearly single-mode semiconductor waveguide-coupled ring and disk microcavity optical resonators. Using a novel 10.5-μm-diameter ring resonator, we measure transverse electric (TE) and transverse magnetic (TM) field intensity losses in 0.35-μm-wide ring waveguide cavities in the 1.55-μm-wavelength region. We present the experimental results for nanofabricated AlGaAs/GaAs 10.5-μm-diameter ring and disk resonators to quantify cavity losses and to show the feasibility of these promising and robust submicron-scale devices.
