Conventional PIN diodes are capable of switching high levels of power with minimum loss and distortion. However, to electrically switch these devices requires high voltage switching power supplies. An alternate approach is to utilize high power PIN diodes with integral optical windows activated by high pulse power 2-D laser diode arrays: Rosen et al. have demonstrated hf (2-30-MHz) switches utilizing this concept.1 They reported that the ratio of the time for which the switch remained closed to the time for which the pulsed laser diode array was emitting IR energy was as great as 5 (we will refer to this ratio as the R factor) with bias currents of 3.6 A at 400 V.
