Abstract

This paper reports on the first observations of a promising new form of optically triggered modal bistability in semiconductor lasers. The bistable mechanism involves a switch between the degenerate in-phase and antiphase coupled modes of an index-guided, twin-ridge laser operating at 1.3 μm wavelength. Experimental results have indicated sub-picojoule bistable switching with switching times of less than 250 ps. Possible limitations of device performance are discussed, with particular reference to asymmetry of the ridge structure.
