In the present work the authors demonstrate the possibility to perform logical AND operations and NOT operations based on all-optical switching in a 1D photonic crystal (PhC) tapered nanocavity fabricated in SOI silicon photonic wire (PhW) waveguide. After an initial characterization of the optical response of the system by means of linear waveguide transmission, all-optical logical operations were...
A monolithic semiconductor ring laser (SRL) is demonstrated to operate as an optical monostable and bistable that can be triggered by an optical pulse, showing potential for all-optical 2R regeneration and all-optical Flip-Flop applications.
Summary form only given. Semiconductor ring lasers (SRLs) are promising devices for all-optical switching applications, as they can operate in a directional bistable regime where only one mode (clockwise or anti-clockwise) is active at one time. Directional switching can be triggered by the injection of an external optical signal pulse. We report on the design, fabrication, and characterization of...
Optical discrete solitons possess extremely interesting dynamical properties. Such properties lead to the realization of several ultrafast, all-optical switching mechanisms, based on the use of uniform and nonuniform waveguides array.
