After dominating the electronics industry for decades, silicon is on the verge of entering the field of integrated photonics - the traditional stronghold of III–V semiconductors. The development of silicon based photonics lags far behind, despite silicon nano-fabrication methods being extremely well developed. This is primarily due to lack of practical silicon light sources, i.e., efficient silicon light-emitting diodes and injection lasers.
The reason is that silicon is an indirect-band-gap semiconductor material for which light emission is a phonon mediated process with a low probability. This gives rise to spontaneous e-h recombination lifetimes in the millisecond range, much longer than the typical timescale for non-radiative recombination. As a result, the internal quantum efficiency for intrinsic silicon is very low. With regard to lasing in silicon, fast and efficient non-radiative processes such as Auger or free-carrier absorption prevent population inversion at the high pumping rates needed to achieve optical amplification.
The overall aim of my work is to develop efficient monolithic light sources on a silicon chip. I am investigating two different approaches employing nanophotonic effects from passive silicon photonic crystal nanocavities and germanium-islands  as active emitter in a silicon photonic crystal nanocavities.
