On-chip near-infrared optical spectrometer based on single-mode Epo waveguide and gold nanoantennas

Toralf Scharf, Irène Antoinette Philipoussis, Joab Di Francesco

We report about optical spectrometry using gold nanostructures printed on top of an integrated optical waveguide. The optical waveguide is a single-mode buried waveguide made from a combination of photo-polymerizable materials and is fabricated by photolit ...

Manipulating Bloch surface waves in 2D: a platform concept-based flat lens

Hans Peter Herzig, Tristan Sfez, Libo Yu, Elsie Barakat, Lubos Hvozdara, Joab Di Francesco

At the end of the 1970s, it was confirmed that dielectric multilayers can sustain Bloch surface waves (BSWs). However, BSWs were not widely studied until more recently. Taking advantage of their high-quality factor, sensing applications have focused on BSW ...

CO2 isotope sensor using a broadband infrared source, a spectrally narrow 4.4 μm quantum cascade detector, and a Fourier spectrometer

Hans Peter Herzig, Lubos Hvozdara, Joab Di Francesco

We report a prototype CO2 gas sensor based on a simple blackbody infrared source and a spectrally narrow quantum cascade detector (QCD). The detector absorption spectrum is centered at 2260 cm−1 (4.4 μm) and has a full width at half maximum of 200 cm−1 (25 ...
