Optical square-wave generation in a diode-laser array.
We describe a new mechanism for passive generation of rapid-rise-time, high-bandwidth optical square waves based on directional switching. By using a diode-laser array in an external optical cavity, square-wave optical signals as fast as 250 MHz with detector-limited rise times of less than 200 ps are generated.
