Abstract

PURPOSE:To make the forward bias to diode unnecessary, to reduce the power consumption and to speed up the operation, by constituting the photodiodes to be used with the 1st semiconductor having pn junction and the 2nd semiconductor having less energy forbidden band than the 1st semiconductor. CONSTITUTION:On P or N type semiconductor 7, N or P type semiconductor 8 opposite to this conduction type, is provided, pn junction 9 is formed, and semiconductor 10 is provided on the semiconductor 8, which has smaller energy forbidden band than that of the semiconductor 8 and is of the same conduction type as the semiconductor 8, and photodiode 16 is made by forming the hetero junction 11. With the diode 16 of this constitution, the optical signal converting the input electric signal Ai into light 2 by the electro-optical conversion element 1 is received, the bias of the diode 16 is switched with the switch circuit 5 to output a signal corresponding to the input signal Ai at the output terminal 15. Further, the forward bias to the diode 16 is made unnecessary, the power consumption is reduced, and high speed operation is made possible.
