TL;DR: It is shown that simple size scaling by replacing bulky discrete optical elements used in conventional IR spectroscopy with their on-chip counterparts is not a viable route for on- chip infrared spectroscopic sensing, as it cripples the system performance due to the limited optical path length accessible on a chip.

Designing mid-wave infrared (MWIR) thermo-optic coefficient (dn/dT) in chalcogenide glasses
TL;DR: In this article, the role of chemistry and structure on mid-wave infrared (MWIR) optical properties was investigated using 17 infrared-transmitting GeAsSe chalcogenide glasses.

Femtosecond direct-writing of waveguide in non-oxide glasses
Arnaud Zoubir,Martin Richardson,Cedric Lopez,Laeticia Petit,Kathleen Richardson,Clara Rivero,Alfons Schulte +6 more
TL;DR: In this paper, the fabrication of waveguides in optical materials using a femtosecond laser was described, which has the unique advantage of allowing volume structures to be fabricated.

TL;DR: In this paper, a non-perturbative design that enables low-loss device operation beyond the traditional figure-of-merit limit is presented. But, the design rationale is to engineer the light propagation path through the OPCMs when it is in the low-layer amorphous state, and divert light away from the lossy crystalline state leveraging the large mode modification induced by the O-PCM phase transition.
