Development and Application of Light Activated Silicon Switches.
Abstract
Light activated silicon switches (LASS) were fabricated and devices tested in a flexible test modulator built specifically for LASS testing. Various types of light triggering were investigated including radiation from GaAs laser diode, xenon flash lamp, incandescent lamp and Q-switched neodymium (Nd3+) laser. Devices were fired singly and in series at pulse currents of 500 amperes and dI/dt's of 1000 amps/microseconds using GaAs laser diodes as light trigger. Using the Q-switched Nd3+ laser resulted in extremely high speed device turn-on with forward voltage transient over in 20 nanoseconds. A redesign of the early prototype encapsulation was necessary to achieve large pulse current capability. (Author)
