Broadband mId-infrared semiconductor modulators – BIRD
Fast amplitude and phase modulation is essential for a plethora of applications in photonics, including laser amplitude/frequency stabilisation, coherent detection, optical communications, spectroscopy, gas sensing etc. In the mid-infrared (MIR) wavelength range (3-12um) broadband MDs are missing, hampering the progress of MIR photonics. In this project we aim at demonstrating two types of power efficient and broadband (up to ~40GHz bandwidth) integrated MIR amplitude- and phase-MDs, suitable for industrial production, that will be capable of addressing the needs of emerging MIR photonics applications. The frequency response of these devices (optimised in the 9.5-10.5um wavelength range) will be fully characterised using an in-house fabricated ultra-broadband (>70GHz) detector and a VNA analyser. Finally, the potential of the MDs for spectroscopy/gas sensing applications will be demonstrated by setting up an original high resolution-spectroscopy experiment.
