Abstract
All optical Boolean logic devices have the potential to perform many important operations in future all-optical, high speed communications networks. Some advantageous uses may be in bit pattern matching [1], pseudo random number generation [2], optical label swapping [3], and encryption [2]. Performing such operations optically is desirable in the effort to overcome the speed and power consumption limitations inherent in electronic operations. All of these examples rely on Boolean exclusive-OR (XOR) functionality, in which output is nonzero if and only if one of two input signals is a logical 1 and the other is a logical 0
