Using a compact (0.03 mm(2)) silicon-photonic bias-free thermo-optic cross-bar switch, we demonstrate microsecond-scale switching of twenty wavelength channels of a C-band wavelength-division multiplexed optical ring network, each carrying 10 Gbit/second data concurrently, with 15 mW electrical power consumption (no temperature control required). A convenient pulsed driving scheme is demonstrat...

High voltage multi-gap gas discharge switches are very important tools for pulsed power applications in accelerator laboratories. They have applications for example in driving fast injectionand extraction magnets and beam dumps. Basically, there are two different principles used to realise a high voltage switch. One is based on the use of several semiconductor switches, and the other is based o...

The 1-MW High Voltage Converter Modulators [1] have operated in excess of 250,000 hours at the Spallation Neutron Source. Increased demands on the accelerator performance require increased modulator reliability. An effort is underway at SLAC National Accelerator Laboratory to redesign the modulator H-bridge switch plate with the goals of increasing reliability and performance [2]. The major dif...

The need for high voltage solid-state power electronic devices for advanced power distribution and energy conversion has grown rapidly in recent years, especially for pulsed power applications that require high turn-on di/dt. However, current power converters built with silicon (Si) switches are quite bulky and inefficient, making their utilization difficult in practical energy conversion and p...

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...

In high-power applications, opening switches play an important role. These switches are required to carry high currents (100 A-10 MA) and operate with short switching times ( l0ms-Ions). Moreover, before opening, the switch must conduct current to a parallel circuit branch (load) and withstand the voltage across the load. If there is no load in parallel to the switch, it must absorb all the ene...

There has been considerable interest in recent years in using inductive storage techniques for pulsed power applications. Some of the advantages that inductive generators have over the more conventional capacitive systems include higher final stage energy density for higher power and smaller generators, lower insulator stress, faster pulse risetime, and the possibility of shorter pulse length. ...
