Abstract
PURPOSE:To prevent an optical output from fluctuating due to a variation in temperature by a method wherein a laser diode and an electric heating body are formed on a common wafer to be adjacent to each other or to be close to each other and these are united as one chip. CONSTITUTION:A laser diode chip 13 is constituted in such a way that a general laser diode 13L and an electric heating body 13H are formed in an active layer 13A to be adjacent to each other. The laser diode 13L and a laser diode whose characteristic is identical to that of the diode are formed side by side on one wafer; after that, an overcurrent flows to this laser diode; this diode is broken down and is used as the electric heating body 13H. Accordingly, an electric heating characteristic of the electric heating body 13H is nearly equal to that of the laser diode 13L. The laser diode chip 13 is arranged in such a way that the active layer 13A is perpendicular to a stem 11; a laser beam 14 radiated from the laser diode 13L is irradiated to the outside of a case through a window 16 installed in the central part of a cap 15.
