Dual-wavelength laser for THz generation by photo-mixing


We present the design and the fabrication of a dual-wavelength micro-photonic resonator combining a photonic crystal membrane (PCM) and a vertical Fabry Perot (FP) cavity where the former is embedded in the latter. A strong optical coupling between a PCM Γ-point Bloch mode and a FP mode at the same frequency can be used to provide a dual-wavelength device with a frequency difference which is analysed in terms of modes overlapping. We propose and demonstrate a process flow that can be used to provide such a device. Optical reflectivity characterisation is presented for a monolithic device and photoluminescence dual-wavelength spontaneous emission is demonstrated in an extended vertical cavity. Finally the dual-mode laser emission stability is examined with numerical Monte Carlo simulation.
