  • Patent number: 4883334
    Abstract: The present invention pertains to an optical selector switch. The optical selector switch includes an optical waveguide means, and M means for producing light that can be transmitted through the optical waveguide means with M being greater than or equal to 2. The M light producing means are optically connected to the optical waveguide means. The optical selector switch includes means for controlling when each of the M light producing means produces optical pulses to be transmitted through the optical waveguide means. Additionally, there are N optical transduces optically connected to the optical waveguide means, with N being greater than or equal to 2. Each of the N optical transducers are capable of producing an electrical signal corresponding to the combination of optical pulses received from the M light-producing means. The N optical transducers can be arranged in either a one, two or three dimensional array. Moreover, memory cells can be included to provide for a memory array.
