Ultrafast All-Optical Wavelength Routing of Data Packets Utilizing an SOA-Based Wavelength Converter and a Monolithically Integrated Optical Flip–Flop
IEEE journal of selected topics in quantum electronics(2008)
摘要
We demonstrate all-optical wavelength routing of 80 Gb/s data packets without using electronic control. The system consists of an optical wavelength converter and a monolithically integrated optical flip-flop memory. The integrated optical flip-flop is based on two coupled lasers, exhibiting single-mode operation, having a 35 dB contrast ratio between the states, and switching its state in about 2 us. The wavelength converter is optically controlled by the optical flip-flop. We show that the optical set and reset pulses can force the optical flip-flop to switch its continuous-wave output light between two specific wavelength positions. The output light feeds the wavelength converter, which, in turn, converts the data packet into the flip-flop's output wavelength, causing the data packet to be routed into a specific port.
