Abstract
A new family of optical logic gates is presented. The two inputs of these devices are separated by wavelength, thus isolating the two signals and reducing cross talk. Experimental results showing the operation of the optical set-reset memory, optical inverter, optical gated latch, optical AND gate and NAND gate are presented. Output on/off contrast ratios ranging from 6 up to over 50 have been obtained.
