We report on the fabrication and characterization of a two-dimensional photonic crystal (PC) embedding two InGaAs quantum dot layers as active light emitters. Light confinement was provided by both a PC GaAs slab waveguide and a distributed Bragg reflector (DBR) located at the bottom of the guiding layer.

Abstract

We report on the fabrication and characterization of a two-dimensional photonic crystal (PC) embedding two InGaAs quantum dot layers as active light emitters. Light confinement was provided by both a PC GaAs slab waveguide and a distributed Bragg reflector (DBR) located at the bottom of the guiding layer. The micro-photoluminescence characterization shows that the photonic crystal can be used to alter the quantum dot emission by modifying the photonic density of states.
