Electrically reconfigurable phase-change transmissive metasurface
Cosmin Constantin Popescu, Kiumars Aryana, Parth Garud +12
Programmable and reconfigurable optics hold significant potential for transforming a broad spectrum of applications, spanning space explorations to biomedical imaging, gas sensing,…
Versatile spaceborne photonics with chalcogenide phase-change materials
Hyun Jung Kim, Matthew Julian, Calum Williams +6
Recent growth in space systems has seen increasing capabilities packed into smaller and lighter Earth observation and deep space mission spacecraft. Phase-change materials (PCMs) a…
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…
