This paper reports on the design of a multipurpose photonic device based on 2-D photonic crystals which uses Y couplers in its structure that is very efficient when employed as a switch in optical communication systems and possesses a very high sensitivity not only if used as a biophotonic sensor to detect refractive index changes but also as a pressure sensor to sense pressure changes. The performance...
A highly sensitive pressure sensor operating over a wide pressure range based on two-dimensional photonic crystals having a Mach-Zehnder interferometer structure has been developed. The plane wave expansion method (PWE) is used to determine the device operating wavelength range. The finite difference time domain method (FDTD) is used to calculate the device characteristic parameters such as the resonant...
