A  W electrode gate (19) is formed  within  a  GaAs  crystalline  layer (21), and an SiO2 oxide layer (20) is formed upon a GaAs substrate (1) and on the opposite sides of the GaAs crystalline layer  (21). An AuGe/Ni layer (15) is deposited on the GaAs  crystalline  layer (21) for realizing an n type contact. When the resistance  between the source and the drain is varied due to a  light  absorption  by applying a voltage there, the positive holes which are  formed  by applying a reverse voltage are pulled  through  the  W  electrode, thereby improving the recovery time characteristics of the device.
