| description | The development of compact and fieldable mid-infrared (mid-IR) spectroscopy devices
represents a critical challenge for distributed sensing with applications from gas leak
detection to environmental monitoring. Recent work has focused on mid-IR photonic integrated circuit (PIC) sensing platforms and waveguide-integrated mid-IR light sources and
detectors based on semiconductors such as PbTe, black phosphorus and tellurene. However,
material bandgaps and reliance on SiO2 substrates limit operation to wavelengths λ ≲ 4 μm.
Here we overcome these challenges with a chalcogenide glass-on-CaF2 PIC architecture
incorporating split-gate photothermoelectric graphene photodetectors. Our design extends
operation to λ = 5.2 μm with a Johnson noise-limited noise-equivalent power of 1.1 nW/Hz1/2,
no fall-off in photoresponse up to f = 1 MHz, and a predicted 3-dB bandwidth of f3dB > 1 GHz.
This mid-IR PIC platform readily extends to longer wavelengths and opens the door to
applications from distributed gas sensing and portable dual comb spectroscopy to weatherresilient free space optical communications. |
