摘要： An optical interconnection network in which more than one communication can occur at any given time is disclosed. The interconnection network can form part of a parallel computer, a fiber optic switching network, a massive video or data server or an asynchronous transfer mode (ATM) network. The network includes transmission network elements (12a), reception network elements (12b) and a holographic storage element (14). The holographic storage element (14) is located equidistant from all the transmission (12a) and reception (12b) network elements and stores therein a multiplicity of volume holograms. Each volume hologram is responsive to a different angle of incidence of wavelength. Each transmission network element (12a) includes a light directing unit which selectively provides at least one light beam of at least one desired angle of incidence to the holographic storage element (14) which, in turn, redirects each light beam towards a corresponding one of the reception network elements (12b) in accordance with the one of the volume holograms responsive to the corresponding angle of incidence.

摘要： Pulse-width modulation (PWM) drive circuitry particularly applicable to an array of electrostatic actuators formed in a micro electromechanical system (MEMS), such as used for optical switching. A control cell associated with each actuator includes a register (222) selectively stored with a desired pulse width. A clocked counter (220) distributes its outputs to all control cells. When the counter matches the register, a polarity signal corresponding to a drive clock is latched and controls the voltage applied to the electrostatic cell. In a bipolar drive, one actuator electrode is driven by a drive clock (CLK); the other, by the latch (228). The MEMS element may be a tiltable plate supported in its middle by a torsion beam. Complementary binary signals may drive two capacitors formed across the axis of the beam. The register and comparison logic for each cell may be formed by a content addressable memory.

摘要： The invention relates to a device and a method for switching optical wavelength channels. Said optical wavelength channels are introduced into at least one access waveguide provided on a first side of a first multi-mode waveguide (10). Subsequently, the wavelength channels are transmitted through said multi-mode waveguide (10) and projected on at least two connection waveguides provided on the opposite side. Subsequently, the optical wavelength channels are transmitted through the connection waveguides. For each wavelength selective cross-connection structure (2, 4, 6, 8) the phase is changed for a reflecting wavelength of two phase control elements (C1, C2, D1, D2, E1, E2, F1, F2) arranged in a first and a second connection waveguide on a first side of said wavelength selective cross-connection structure (2, 4, 6, 8), simultaneously as at a second side of said wavelength selective cross-connection structure (2, 4, 6, 8) said reflecting wavelength phase remains relatively unchanged. For each wavelength selective cross-connection structure (2, 4, 6, 8) the phase is changed for transmitting wavelengths once in a first and a second direction per wavelength selective cross-connection structure (2, 4, 6, 8). The phase difference between the optical signal in each access waveguide provided on the first side of the second multi-mode waveguide (20) determines where the optical signal is focused on the opposite side.
