摘要： A driving method of the present invention drives a semiconductor laser which is provided with at least first and second electrodes through each of which current is injected into the semiconductor laser. Varying current is injected through the first electrode when the frequency of the varying current is in a high frequency band. Varying current is injected through the first electrode while phase-shifted current, whose phase is shifted relative to the varying current, is injected through the second electrode, when the frequency of the varying current is in a low frequency band which is lower than the frequency of the high frequency band. Feedback-control may be performed for controlling a ratio between amplitudes of the modulation current and the phase-shifted current based on a light output from the semiconductor laser. The varying current includes at least modulation current modulated according to a predetermined signal or negative feedback current produced by an electric signal obtained by detecting fluctuation of oscillation wavelength of a light output from the semiconductor laser. Thus, an optical signal radiated from the laser can be desirably stabilized over a wide frequency band range.

摘要： A wavelength control method controls a wavelength of output light from an optical transmitter used in an optical communication system for performing wavelength-multiplexing. The method includes steps of causing light-output means of the optical transmitter to output light and guiding the output light of the light-output means and light used in the optical communication system to a wavelength tunable filter. The method also includes sweeping a selective wavelength of the wavelength tunable filter, and detecting, based on the sweeping, if a wavelength spacing between a wavelength of the output light, which is output from the light-output means, and a wavelength of the light used in the optical communication system, which is adjacent to the wavelength of the output light on a wavelength axis on either a longer wavelength side or a shorter wavelength side, is wider or narrower than a predetermined wavelength spacing. The method also includes performing control in which the wavelength of the output light is caused to approach the adjacent wavelength when the wavelength spacing is detected to be wider than the predetermined wavelength in said detecting step and the wavelength of the output light is caused to be away from the adjacent wavelength when the wavelength spacing is detected to be narrower than the predetermined wavelength.

摘要： In an optical communication system for performing wavelength division multiplex communication on an optical transmission path, an output light wavelength control is performed as follows in an optical transmitter. A wavelength of light on the optical transmission path is detected so as to search for an unoccupied space, in which output light from the self optical transmitter does not cause an interference with another light on the optical transmission path. The wavelength of the output light from the self optical transmitter is controlled so as to be a wavelength falling within the unoccupied space. A wavelength of another light which is adjacent to the wavelength of the output light from the self optical transmitter on one of the longer and shorter wavelength side along a wavelength axis is set as a reference side wavelength, so that the wavelength of the output light is controlled to set a wavelength interval between the reference side wavelength and the wavelength of the output light from the self optical transmitter to be close to a predetermined first wavelength interval or to maintain the wavelength interval to have a value in the neighborhood of the predetermined first wavelength interval.

摘要： In a light source apparatus, the polarization mode of oscillation light from a semiconductor laser is switchable between two different polarization modes when a modulation current is injected into a portion of a light waveguide of the semiconductor laser. Light in one polarization mode and light in the other polarization mode are separately obtained from the oscillation light from the semiconductor laser. At least the light in one of the two different polarization modes is converted to an electric signal. Current injected into the semiconductor laser is controlled based on the electric signal such that a modulation state of light from the semiconductor laser is stabilized. The light in the other polarization mode, or light in one polarization mode emitted from the other emission side of the semiconductor laser may be used for optical transmission.
