ENHANCED TEMPERATURE SENSING BY USING ONE-DIMENSIONAL TERNARY PHOTONIC BAND GAP STRUCTURES

By A. Banerjee

Abstract:
This paper demonstrates a novel way to enhance the temperature sensitivity in one-dimensional (1D) photonic band gap (PBG) material by using a ternary periodic structure (i.e. three material layers constituting a period of lattice). The temperature sensitive wavelength band shift of (Si/SiO2) periodic structure was significantly enhanced when the structure was modified by sandwiching a thin layer of Bi4Ge3O12 between every two layers, constituting a period of lattice. When the thickness of sandwiched layer was increased further enhancement in temperature sensitivity was observed. These 1D ternary PBG structures can be substituted in place of 1D binary PBG for enhancing the temperature sensing performance.
