In this paper, we consider the construction of an optical priority queue with a single (M + 1) × (M + 1) switch and M fiber delay lines. The M fiber delay lines are connected from M outputs of the switch back to M inputs of the switch, leaving one input (resp. output) of the switch for the input (resp. output) of the priority queue. It was known in [8][9] that with an appropriate choice of the ...
We propose a hybrid optical-electrical switch architecture which integrates all-optical waveband switching and electrical time-division-multiplexed (TDM) switching. By grouping pass-through traffic into wavebands and switching them alloptically, the hybrid architecture can significantly reduce the size of electrical switch and number of associated transponders. As a result, it provides tens of ...
In the recent years reversible logic design has promising applications in low power computing, optical computing, quantum computing. VLSI design mainly concentrates on low power logic circuit design. In the present scenario researchers have made implementations of reversible logic gates in optical domain for its low energy consumption and high speed. This study is all about designing a reversib...
Operation without packet alignment of an all-optical packet switch is proposed and predicted feasible through a detailed trafic analysis. Packet alignment units are eliminated resulting in a simple switch architecture while optimal traffic perfarmancc is maintained through t ~ i e ~ e x ~ b i ~ ~ ~ ~ r o v ~ d e d by WDM.
We demonstrate all-optical switching of 20 wavelength channels simultaneously in a silicon broadband comb switch, and perform single-channel BER measurements through both ports.
Watt three-stage Q-band MESFET monolithic power amplifier'. Fig. 1 Packerpipping scheme for packet synchronisation Within this frame, however, the packet may Hoat. If such traffic is presented to an all-optical packet switch with slot size equal to the frame size (i.e. with twice as long slot size), the switch preserves the 'one packet per frame' rule. However, if this traffic coming from the o...
To test the hypothesis that the same mechanisms mediate form deprivation and lens-induced myopia, the ocular growth responses of chicks alternately exposed to lenses and diffusers at regular intervals (3h) were compared to those of chicks exposed to either negative lenses or diffusers alone. In total, there were four experiments: (1) -15 D lenses and/or diffusers on normal birds, (2) -15 D lens...
The urgent need for high-bandwidth and high-port connectivity in Data Centers has boosted the deployment of optoelectronic packet switches towards bringing high data-rate optics closer to the ASIC, realizing optical transceiver functions directly at the ASIC package for high-rate, low-energy and low-latency interconnects. Even though optics can offer a broad range of low-energy integrated switc...
Photonic circuits require elements that can control optical signals with other optical signals. Ultra-low-light-level operation of all-optical switches opens the possibility of photonic devices that operate in the single-quantum regime, a prerequisite for quantum-photonic devices. We describe a new type of all-optical switch that exploits the extreme sensitivity to small perturbations displayed...
