Abstract

We report on the design and demonstration of novel photonic crystal (PC) cavities. The cavity active region is made of a macro-porous silicon infiltrated with optically active lead sulfide thin films (emitting at a wavelength of about ∼2.9 μm), while the surrounding silicon PC acts as a mirror that confines the infrared light. The luminescence spectrum of the composite PC cavity presents a set of resonant frequencies associated with the cavity modes that overlap with the photonic stopbands of the host silicon PC.
