Abstract

We investigate the change of the photonic band structure of the Suzuki-phase photonic crystal lattice when the transversal symmetry is broken by an underlying Bragg reflector. The structure consists of an InP photonic crystal slab including four InAsP quantum wells, a SiO2 bonding layer, and a bottom high index contrast Si/SiO2 Bragg mirror deposited on a Si wafer. Polarization-resolved angle-resolved photoluminescence spectroscopy has been used for measuring the photonic band structure. An important change in the photonic band structure between the structure with and without Bragg reflector is measured. An enhancement on the photoluminescence emission up to seven times has been obtained also for a particular photonic band.
