چکیده
In this paper, Standard Sampled Grating array is designed and 2D simulation is performed with Finite difference method. Implementation of Different types of subwavength Grating structures are discussed and analyzed with simulation result. The power Reflectivity at different wavelength under the variation of different grating parameters is demonstrated on the simulation. Grating periods, grating spacing and grating removal are the parameters varied for the Reflectivity analysis and also effects of the parameters on Reflectivity are studied. Reflectivity of Sampled Grating array is observed as 99.8% at multiple wavelengths. Such type of Sampled Grating array structure used as a optical reflector for Multichannel Optoelectronic devices. Keywords— Subwavelength grating; Reflectivity; Finite difference.
