InGaP microdisk optical resonators are embedded in indium tin oxide (ITO) to investigate how the optical absorption in electrodes impacts the resonance properties. The quality factor is slightly reduced in comparison with air-embedding microdisks, and the measured quality factor is 960 for a 1.2 μm diameter, 170 nm thick disk embedded in ITO media. The experiments show that the absorption loss in ITO media has smaller contribution to the reduction of total quality factor than the scattering and radiation losses. The analysis indicates that the suppression of non-absorption loss would improve the quality factor to 10^4.
