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.

We fabricated single mode Ge28Sb12Se60 waveguides and resonators using e-beam lithography and achieved a propagation loss of 3.88 dB/cm at 3.66 µm. We compared BCl3 and CHF3 etch chemistries and determined CHF3 produced 1.5 dB/cm higher propagation
