An electromagnetically induced absorption grating is formed in a three-level atomic vapor under the condition of electromagnetically induced transparency in which the strong coupling beam is replaced by a standing wave. The transmission and reflection behaviors of the weak probe beam are greatly modified at certain frequencies near the two-photon resonance. An all-optical two-port signal router...

Due to the increasing growth of processing cores in complex computational systems, all the connection converted bottleneck for all systems. With the protection of progressing and constructing complex photonic connection on chip, optical data transmission is the best choice for replacing with electrical interconnection for the reason of gathering connection with a high bandwidth and insertion lo...

in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

The hardware architecture of a 5-Tbit/s FB (Frame-Based) ATM switching system OPTIMA-2 ( m i c a l l y Interconnected Distributed Multi-stage Tbit/sATM switching Network Architecture -2 ) is described. OPTIMA-2 has a non-blocking 3-stage switch architecture employing optical WDM links and dynamic bandwidth sharing. The WDM links are composed of a sender port, wavelength AWG router and receiver ...

For the first time, the feasibility of large port count nanosecond reconfiguration time optical switches is demonstrated using a novel hybrid approach, where Mach-Zehnder interferometric (MZI) switches provide low loss high speed routing with short semiconductor optical amplifiers (SOAs) being integrated to enhance extinction. By repeatedly passing signals through a monolithic hybrid dilated 2...

In the past years, electronic routers have had trouble keeping up with the increase in optical fiber capacity. As their power consumption has grown exponentially and already exceeds standards, it seems that an alternative solution is mandatory. Many have suggested all-optical routers as an alternative. However, these are deemed too complex, especially given the need to implement both switching ...

Synchronisation is an important and critical issue in high-speed all optical time division multiplexed (OTDM) packet routing and transmission. In this paper we present a technique for separating the clock synchronization pulse from an incoming optical time division multiplexed data packet, based on all-optical switching devices with optical feedback. A 1X2 OTDM router composed of three Symmetri...
