People living in slums are severely affected in case of any disaster such as fire or earthquake due to the unawareness of the situation and difficulties associated with rescue operations. Since disaster preparedness and responses are always better than recovery, our goal is to aware habitats for faster response during the disaster occurrence such as fire breakthrough. Conventional fire alarm systems...
Design and simulation of all optical NOT and XOR gates based on 2D photonic crystal with quasi-square ring cavity are reported in this paper. The designed 13µm×8µm photonic crystal has a square lattice of GaAs rods in air with refractive index of 3.40 at operating wavelength of 1.55 µm. The lattice constant, a = 0.540 µm and radius of rods, r = 0.185a µm are chosen so that a large band gap for a TE...
