광효과를 이용한 GaAs MESFET의 광 제어
Optical Control of GaAs MESFET with Optical Effect
초록
In this paper, using optical effect of characteristics of GaAs compound, two potential application of optical controlled GaAs MESFET are demonstrated` detector, microwave amplifier gain control. These lead to the possibility of the interaction with optical devices. The preliminary experiments show the light induced voltage, the increase in the drain currnet and the change in the microwave scattering parameters of GaAs MESFET under optical illumination(He-Ne laser). And imcrowave amplifier gain is round to be varied with changing in intensity of optical illumination.
