G. Cancellieri et al., COUPLED-SOLITON PHOTONIC LOGIC GATES - PRACTICAL DESIGN PROCEDURES, Journal of the Optical Society of America. B, Optical physics, 12(7), 1995, pp. 1300-1306
The feasibility of AND, OR, and EX-OR functions based on the interacti
on of optical solitons is proved by use of a five-layer dielectric str
ucture with a nonlinear core. With the exception of the OR logic gate,
the design of these devices is rather flexible, offering a wide varie
ty of choices with respect to both the geometrical parameters and the
input power levels.
