Abstract
Interest in bistable optical devices has grown steadily due to the need for a very fast optical switch for optical computing and optical communications. Most of the presently demonstrated bistable devices are designed for these applications and work with input and output data that are optical intensities.1 Another trend that is now receiving increasing attention is the use of wavelength as the information carrier such as in frequency shift keying (FSK), which uses two optical frequencies to represent 1 and 0. This creates the need for devices exhibiting bistability in wavelength. We report new operating characteristics of a wavelength bistable device that can be easily extended to operate as a multistable and chaotic device in wavelength.
