Abstract

The high vertical index contrast and the small thickness of thin InP-based membrane structures bonded with BCB on Silicon allow the realization of very small devices. In COBRA, we aim to make a direct electrically pumped photonic crystal laser in this platform. Together with submicron selective area re-growth and oxidation of AlInAs for the current confinement techniques that we developed previously, a "W1 like" photonic crystal cavity type is designed and simulations in FDTD show good performance in terms of quality factor and tolerance to the manufacturing imperfections. Simulations show that doping and oxidation of AlInAs does have a negative effect on the Q factor, yet it is acceptable. All in all, we expect to make electrically injected photonic crystal lasers with high pumping efficiency and small threshold current as well as low power consumption.
