A monolithic semiconductor ring laser is operated as an all-optical set-reset flip-flop triggered by external optical pulses. Bit-error-rate measurements of set-reset switchings under the injection of a pseudo-random-bit-sequence have been performed, showing reliable operation up to 10 Gb/s.
In this work, the authors report on the demonstration of a monolithic semiconductor ring laser (SRL) as an all-optical set-reset flip-flop (SRFF). The SRL has a racetrack cavity, with 150 mum radius connecting two straight sections of 200 mum. Two straight output waveguides provide 4 input/output ports that can be used to inject/extract optical signals. The devices operate continuous wave at room...
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.
A monolithic semiconductor ring laser (SRL) is demonstrated as a fully all-optical flip-flop that can be triggered by optical pulses of 400 ps duration, showing 130 ps response time.
A semiconductor ring laser all-optical flip-flop is used to realize all-optical label swapping. Old address is erased by blocking the switching optically and new address is inserted by modulating the output from SRL.
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.
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...
