We present a photonic crystal (PhC) biperiodic waveguide (BPW) structure for both gas and fluid sensing based on modulation of refractive index (RI) of supercavities. The proposed structure has been designed by creating a BPW in silicon (Si) substrate with triangular array of air holes. This BPW structure consists of an array of supercavities and only the resonant wavelength is allowed to pass through...
In this paper, we have investigated Photonic Band Gap (PBG) of two dimensional Photonic Crystals (PhCs) for TE polarization. Effect of shape, size and orientation of scatteres on PBG in triangular lattice has been investigated. OptiFDTD software has been used to calculate PBG, having simulator, Planewave Band solver, based on plane wave expansion method. The scatterers are air holes in dielectric...
