FDTD approach to photonic based angular waveguide for wide range of sensing application

Photonic based angular waveguide is employed in this communication to envisage a wide range of sensing application with the help of finite difference time domain approach, whereproposed photonic structure is realised by 11 × 11 airholes with elimination of series of holes pertaining to L type bending channel, which would be deployed for solving bending loss issues in photonic integrated circuits. However present research is manipulated with visible, infrared signal which acts as input to focus on evanescent signal to comprehend wide range of sensing application, whose ranges from infrared to ultra violet through visible, where the principle of signal is based on the variation of electric field distribution in the said waveguide.
