Abstract

An electrically injected silicon photonic crystal microcavity light source operating at room temperature is demonstrated. The active gain medium consists of PbSe colloidal quantum dots which are embedded in the photonic crystal and whose emission peak is at 1.55μm. The resonant modes of the microcavity are observed in the device output spectra.
