ABSTRACT:
In a semiconductor optical functional element of a loading resistor integrated type, at least one loading resistor is integrated with the optical functional element. The optical functional element has a structure in which a phototransistor and a light emitting diode are adjacent to each other and are integrated with each other, or a phototransistor and a laser diode are adjacent to each other and are integrated with each other. The optical functional element is characterized in that light is fed back from a light emitting portion of the optical functional element to a light receiving portion thereof and a semiconductor layer is formed as the loading resistor in an uppermost layer of the optical functional element. The loading resistor can be manufactured by using the same manufacturing process as the optical functional element. Therefore, the manufacturing process of the loading resistor is simplified and a resistance value of the loading resistor can be easily controlled by controlling resistivity of a semiconductor.
