Abstract: PURPOSE:To obtain high-speed operation in a simple constitution, by inputting a voltage which is proportional to the current difference between a photovoltaic current generated in a optoelectric transducer means and a reference current set at a specified value, and controlling a driving transistor with said output. CONSTITUTION:A driven laser diode LD generates an optical output Po, which is proportional to a forward current If supplied from a driving transistor Q5.

A voltage Ra.(Is-Iref), which is proportional to a current between the photovoltaic current Is generated in the photodiode PD and the reference current Iref, is inputted to a non-inverted input terminal. Therefore the driving transistor Q5 is controlled so that the photovoltaic current Is is proportional to the reference current Iref based on an output current I0 in the amplifier 4.
