Grating-Assisted All-Optical Switching in CdSSe-Doped Nonlinear Fiber
Abstract
Three experiments were performed during this effort. The first experiment measured the pump induced wavelength shift of a 1550 nm probe signal in a 100 cm CdSSe doped fiber. This initial experiment provided the necessary data which formed the basis for the design of a new all-optical switch. The second experiment was the fabrication of the all-optical switch. The operation of the switch was based upon the pump induced wavelength shift of a probe signal. The presumption that such a switch could be designed to be more stable and have higher contract ratios than a Mach-Zehnder switch or 'loop mirror' all-optical switches was demonstrated. in the process of conducting this work, a design configuration for a three-terminal optical gate was developed. The best on-off switching time was 70 Ps. The third experiment determined the transfer characteristics of the optical gate. The transfer characteristics exhibited similar current-voltage characteristics to an electronic transistor; a basic building block for designing all-optical logic gates.
