Abstract :
The design, fabrication, and application of optically activated switches is described. A 0.25-mm-thick Si p-i-n diode, 3.0 mm in diameter, was tested using an 808-nm 2-D diode laser array (measuring about 2 mm×5 mm) as an optical source. Preliminary testing of a 0.25-mm-thick device has demonstrated a holding voltage of 1000 V and a conduction of 10 A upon activation with 200 W of optical power (the pulse width was 10 μs). The same device, while being pulse biased to 2.0 kV, has demonstrated 20-A pulses (100-ns pulse width) with less than 10-ns risetime. The laser peak power was 500 W
