In this project we develop high resolution thermal imaging systems. As a part of our work we have designed a two-dimensional (2D) photonic band gap (PBG) structure for the temperature mapping of ultra-small structures, such as microelectromechanical systems (MEMS). The operational principle of the device is based on guiding and selecting the specifically tuned wavelengths through the corresponding cavities. We have shown that having processed the intensities, obtained from each cavity, in accordance with the blackbody radiation characteristics and the transmission properties of the structure, the temperature reading of the target in concern can be obtained. Despite many studies concerning guided modes in 2D PBG materials, few such sensor applications are proposed.
