A monolithic semiconductor ring laser is operated as an all-optical flip-flop with a response time of 100 ps. Bit-error-rate measurements of repeated set-reset switchings show error-free operation.
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...
Monolithic semiconductor ring lasers (SRLs) have the potential to simultaneously address two important issues of modern optoelectronic systems for high-speed optical communications: integrability and ultrafast all-optical signal processing. SRLs do not require chip cleaving or refractive index grating for the definition of the laser cavity, and hence they allow to integrate several laser devices on...
