CLASS:PUBLIC
DESCRIPTION:&nbsp\;\nThere is growing interest in mid-wave infrared (MWIR) 
 sensing and imaging technologies with improved sensitivity\, reduced size\
 , and lower weight. These advances are important for bolometry\, thermal i
 maging\, and hyperspectral remote sensing. The ability to manipulate the s
 pectral response of a MWIR detector is essential for selectively detecting
  wavelengths associated with specific materials\, temperature signatures\,
  or chemical species. Controlling the polarization response of the detecto
 r can yield additional capabilities for applications. At the same time\, r
 educing the volume and thermal mass of the absorbing material remains crit
 ical\, encouraging the use of thin-film photonic platforms. In this contex
 t\, metal films and two-dimensional materials such as graphene have shown 
 strong potential for infrared detection.\nThis talk explores two novel app
 roaches to MWIR detection. The first approach introduces ultra-thin\, sub-
 wavelength perforated metal-film absorbers for bolometric sensing\, demons
 trating low-thermal-mass devices with polarization-dependent response. We 
 further expand our studies to achieve multi-resonant responses.\nThe secon
 d approach explores novel tunable graphene-based platforms\, including ang
 le-independent absorption modulation using continuous graphene layers and 
 spectral engineering of graphene nanoribbons to produce multiple absorptio
 n peaks.
