An optical associative neural network with a stochastic thresholding procedure has been demonstrated. The use of stochastic processing drastically improved the convergence rate into the correct global minima (recognition rate). The properties of unde

We show the effect of reflections at the fiber ends on the drift characteristics of a fiber-optic passive ring-resonator gyro. A rotation-detection sensitivity as low as 3 x 10(-5) rad/sec (tau = 30 sec) was obtained by reducing the effect of reflect

A novel type of photodetector called a variable sensitivity photodetector (VSPD) has been developed for an optical implementation of a neural network. The function of the VSPD is a photodetector with functions of both a spatial light modulator and a

The effect of polarization coupling which occurs in the coupler comprising the ring resonator for a fiber-optic ring-resonator gyro was studied. First, it is confirmed theoretically and experimentally that the resonant waveform in the ring resonator
