ABSTRACT:
An optical semiconductor device is disclosed which includes a semiconductor laser having at least an active layer, reflecting means formed on the semiconductor laser for reflecting internal feedback light generated from the semiconductor laser and at least two phototransistors formed on the reflecting means for detecting light having a wavelength substantially identical to that of laser light oscillated from the active layer.
