چکیده انگلیسی


• Polarization independent AND optical logic gate and all-optical logic gates in silicon on insulator photonic crystal is proposed.
• The design consists of honey comb lattice arrangement of air holes of different radii in silicon on insulator substrate exhibiting complete photonic band gap.
• The proposed structures performs as an AND optical logic gate and as all-optical logic gates based on the phenomenon of optical interference and the angle of the reference signal provided.
• Improved values of response period and bit rate are achieved at a wavelength of 1.55 µm for both TE and TM polarization, respectively for both the designs.
• The contrast ratio is calculated for both the polarizations for all the logic gates.

In this paper, we have reported design and analysis of polarization independent all optical logic gates in silicon-on-insulator photonic crystal consisting of two dimensional honeycomb lattices with two different air holes exhibiting photonic band gap for both TE and TM mode in the optical communication window. The proposed structures perform as an AND optical logic gate and all the optical logic gates based on the phenomenon of interference. The response period and bit rate for TE and TM polarizations at a wavelength of 1.55 µm show improved results as reported earlier.
