ABSTRACT:
An optical transmission apparatus characterized by comprising a transmission system for transmitting an optical frequency-division multiplex signal, and an optical reception system which contains a semiconductor laser as a light source for reception and receives the optical signal, wherein the semiconductor laser contains first oscillation wavelength control device for controlling its oscillation wavelength according to temperature and second oscillation wavelength control device for controlling its oscillation wavelength according to carrier density, causes the first oscillation wavelength control device to scan oscillation wavelengths over a range from a first frequency to a second wavelength and simultaneously, causes the second oscillation wavelength control device to change the oscillation frequency, and selects wavelengths in the range from the first wavelength to the second wavelength stepwise sequentially.
