All-chalcogenide glass omnidirectional photonic band gap variable infrared filters

H. Esat Kondakci, Mecit Yaman, Ozlem Koylu, Aykutlu Dana, and Mehmet Bayindir
We report on the design, fabrication, and characterization of spatially variable infrared photonic band gap filter that consists of thermally evaporated, high refractive index contrast, amorphous chalcogenide glass multilayers. Due to graded thickness structure, the filter exhibits a position depend ... [Appl. Phys. Lett. 94, 111110 (2009)] published Wed Mar 18, 2009.
