Abstract
Optical transmitter equipment and a semiconductor laser device are provided. In one example, optical transmitter equipment includes a semiconductor laser driven by a direct-modulated method. The optical transmitter equipment comprises at least a semiconductor laser, the semiconductor laser having an active layer for laser oscillation and a clad region for optical confinement; an emission device capable of supplying optical energy to the active layer in the semiconductor laser; and a drive circuit for the semiconductor laser. The emission device is configured to supply optical energy corresponding to a bias current in the semiconductor laser to the active layer in the semiconductor laser.
