Abstract

Novel effects exhibited by closely coupled twin-stripe lasers are reported. Two forms of bistability have been observed. One effect is possibly caused by switching of waveguiding mechanisms and gain guiding to self-focusing. The second mechanism exhibits a large shift in near-field distribution from one side of the laser to the other. The speed of this bistable switching has been found to be between 800 and 900 ps. The effect of optical injection on bistability is noted. Twin-stripe lasers allow picosecond pulses as short at 20 ps to be generated. The dependence of picosecond pulsewidth on asymmetric waveguiding is considered.
