Tunable mid-wave infrared Fabry-Perot bandpass filters using phase-change GeSbTe
Calum Williams, Nina Hong, Matthew Julian +2
We demonstrate spectrally-tunable Fabry-Perot bandpass filters operating across the MWIR by utilizing the phase-change material GeSbTe (GST) as a tunable cavity medium between two…

All-optical continuous tuning of phase-change plasmonic metasurfaces for multispectral thermal imaging
Matthew N. Julian, Calum Williams, Stephen Borg +2
Actively tunable, narrowband spectral filtering across arbitrary optical wavebands is highly desirable in a plethora of applications, from chemical sensing, hyperspectral imaging t…
