Abstract

Transparent conductive oxide (TCO) films are proposed as electrode materials for direct current injection optical microcavity devices. Four types of planar indium-tin-oxide (ITO) clad optical microcavities -1-D photonic crystal nanobeam, 2-D photonic crystal slab, 3-D photonic crystal and microdisk are designed and analyzed both by perturbation theory and 3D finite difference time domain (FDTD) analysis. The quality (Q) factors of cavities obtained by perturbation theory in which imaginary part of the dielectric constant of ITO is introduced as a perturbation agree with those obtained from FDTD method. Microcavities analyzed in this work still preserve high Q-factor in the presence of metal clad and would provide an excellent heat sink and efficient carrier injection for electrically-driven continuous-wave, room-temperature microlasers.
