Abstract:The spontaneous emission rate and Purcell factor of selfassembled quantum wires embedded in photonic crystal micro-cavities aremeasured at 80 K by using micro- photoluminescence, under transient and steady state excitation conditions. The Purcell factors fall in the range 1.1 - 2 despite the theoretical prediction of ?15.5 for the figure of merit. We explain this difference by introducing a polarization dependence on the cavity orientation, parallel or perpendicular with respect to the wire axis, plus spectral and spatial detuning factors for the emitters and the cavitymodes, taking in account the finite size of the quantum wires. © 2012 Optical Society of America.
