GeSbSe Devices for Mid-Infrared Optical Sensing Conference Proceeding uri icon



  • We fabricated GeSbSe waveguides and resonators using e-beam lithography and achieved a propagation loss of 4.4 dB/cm in the mid-infrared region. Using these devices we demonstrated optical sensing of aromatic aldehydes with a limit of detection of 0.25 μmol/mL.
