FAST ELECTRONIC DRIVER FOR OPTICAL SWITCHES Electronically controlled optical switches are critical components in many optical systems, including pulsed lasers. Solid-state optical switches based upon the Pockels effect are widely utilized in research and industry, however Pockels cells require electronic drivers capable of switching several kilovolts quickly and cleanly. This thesis reviews Po...

This paper proposes a novel traffic engineering method for improving the throughput characteristics of optical packet forwarding in an optical packet / path integrated network. This method is based on bypassing optical packets rejected from a highly-loaded optical packet switch onto one of the adjacent packet switches via an optical path to increase the network throughput. Since the formation o...

Systems with coupled cavities and waveguides have been demonstrated as optical switches and optical sensors. To optimize the functionalities of these optical devices, Fano resonance with asymmetric and steep spectral line shape has been used. We theoretically propose a coupled photonic crystal cavity-waveguide structure to achieve Fano resonance by placing partially reflecting elements in waveg...

in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa)  all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...

In this paper, a new structure for cascade multilevel inverter is presented which consists of a series connection of several sub-multilevel units. Each sub-multilevel unit comprises of eight unidirectional switches, two bidirectional switches, and six DC voltage sources. For the proposed cascade topology, two algorithms are presented to produce all possible levels at the output voltage waveform...

We demonstrate that 80 Gb/s data-packets can be all-optically switched into two different ports employing an optical wavelength converter controlled by a monolithically integrated optical flip-flop memory. The optical wavelength converter consists of a semiconductor optical amplifier and an optical filter. The integrated optical flip-flop exhibits single-mode operation, has 35 dB contrast ratio...

This paper presents the design and implementation of an Optical 4:1 Multiplexer using Sagnac Switches as Terahertz Asymmetric Demultiplexers (TOADs). multiplexers play a crucial role in modern communication systems by combining multiple signals onto single optical channel. The proposed multiplexer architecture leverages benefits Switches, such low insertion loss, high extinction ratio, crosstal...

In all internet routers buffers are needed to hold packets during times of congestion. In some recent work, the question of finding the minimum buffer size guaranteeing high throughput has been addressed [3] [6]. The answer to this question is particularly important in building all-optical routers, where the optical technology allows buffering up to a few dozen packets [7]. While in practice mo...

We propose and demonstrate a port-alternated switch-and-select architecture for planar waveguide-based optical switches. The proposed reduces the number of intersections on path, which leads to both small insertion loss path dependence. an 8 × switch based using silicon photonic platform, exhibits fiber-to-fiber 5.7 dB with crosstalk below -30 dB. discuss scalability switch, including propagati...
