A computing system is disclosed including a new optical parametric logic gate. The parametric logic gate includes an optical resonant cavity having nonlinear optical characteristics, such that the cavity will generate a subharmonic output signal having a frequency f when supplied with a pump frequency of 2f. The subharmonic output signal may have one of two possible phases which differ by pi radians to one another, and correspond to binary 1 and 0 respectively. A bias signal having a frequency f is supplied to the resonant cavity. Optical input signals are summed with the bias signal to produce a resultant seed input signal having one of the two phases. The phase of the seed input signal is imparted to the phase of the output subharmonic. The type of logical operation which the parametron performs can be controlled by adjusting the power of the bias signal. The subject disclosure also includes a description of computing systems having various pump arrangements. In addition, data input/output interfaces are disclosed.
