Tree-net architecture for integrated all-optical arithmetic operations and data comparison scheme with optical nonlinear material

A method of generating single optical pulse in nanosecond range with the joint uses of electro-optic modulator and nonlinear material

“…To implement an all-optical processor, the massive use of optical NLM and photo-refractive material based optical switches are seen in many communications [8][9][10][11][12]. A large number of all-optical logic and arithmetic operations can be successfully implemented by isotropic NLMs.…”

An all-optical architecture of serial to parallel converter by using Kerr type of non-linear material

“…In those works, implementation of all-optical logic families, optical combinational and sequential circuits, optical arithmetic units like adders, subtractor, multipliers, optical control units, optical memory units etc. were described [4][5][6][7][8][9]. Optical R-S FlipFlop, optical J-K Flip-Flop etc.…”

“…It is seen that Δθ will have a significant value if pulse LASER instead of continuous LASER is used as input signal. If the intensity of a pulse laser of duration 10 −7 s on time and power of 100 mW incident in NLM made of pure SiO 2 is made double, then the angular separation of the refracted beam (from the NLM) becomes 0.0130 0 from the earlier one, keeping input incident angle fixed at 45 0 [5].…”

A new scheme of implementing all-optical logic systems exploiting material nonlinearity and polarization based encoding technique

“…So a change of the angle of refraction will be obtained which is 1 . 2 2 [12] . Therefore the two paths for the light beam for intensities I and 2 I I are separated from each other and can be identified I physically.…”
