Two-dimensional photonic bandgap mirrors for in-plane microcavities

We demonstrate the use of 2D photonic band gap (PBG) structures such as mirrors for in-plane microcavities, refining previous results for longer 3 /spl mu/m cavities. These structures are an in-plane version of popular vertical microcavities. PBG structures are etched into a GaAs-AlGaAs laser-like heterostructure embedded with self-organised quantum dots (QDs).
