Abstract: A communication system has a first communication system for performing wavelength division multiplexing communications, and a second communication system independent of the first communication system. In the communication system, a wavelength control unit detects the wavelength arrangement in the first communication system, generates a wavelength control signal on the basis of the detected wavelength arrangement, and transmits the wavelength control signal to the respective communication nodes via the second communication system. Each communication node controls its transmission wavelength on the basis of the wavelength control signal. As the wavelength control unit, there are disclosed an arrangement for arranging a wavelength control node independently of the communication nodes, an arrangement using a communication node in a non-receiving state, and an arrangement for assigning the function of the wavelength control unit to a center node.

Abstract: An optical semiconductor apparatus having no polarization dependency and an optical communication system using the semiconductor apparatus are provided. In an optical communication system wherein a signal is demultiplexed by using a semiconductor waveguide type filter disposed on a receiver side, two semiconductor lasers disposed on a transmitter side modulate two light signals having different wavelengths using a common modulation signal and transmit the modulated light signals. One of the different wavelengths is accorded, for example, to the TE mode transmission wavelength of the filter, and the other is accorded, for example, to the TM mode transmission wavelength of the filter. On the receiver side, lights at different wavelengths may be branched into two light portions and the branched light portions may be respectively detected by two photodetectors.

Abstract: 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.

Abstract: A distributed feedback laser selectively performs one of two oscillations in different polarization modes, TE or TM. Two modulation currents are injected into different electrodes of the semiconductor laser having a plurality of electrodes. The relationship between the phases of the two modulation currents is so adjusted that an output waveform is not distorted especially when a modulation frequency is low. Polarization modulation is applied as the modulation form.

Abstract: An optical communication network includes at least one optical transmission path, a plurality of terminals connected to the optical transmission path, a plurality of optical nodes for receiving and transmitting an optical signal between the optical transmission path and the terminals, and a controller for controlling the intensity of a signal output from each optical node so as to equalize its intensity with the intensity of a signal input to each optical node from the optical transmission path. In this optical communication network, the loss of a signal's intensity is determined solely by the total extension length of the optical transmission path, so that the optical nodes can be freely re-connected in the network.
