Composite photonic crystal cavities of macro porous silicon and lead sulfide thin films
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.
