摘要： The transmittance of a filter periodically varies with respect to the incident light frequency. Provided that fk is the sum of Fk and νk, or the difference obtained by subtracting Fk from νk, depending on the kth light source among multiple light sources, an incidence guide causes light from the plurality of light sources to be incident on the filter such that the propagation angle of light when light from the kth light source propagates through the interior of the filter equals θk obtained by computation using fk. The incidence guide causes light to be incident on the filter, taking fk to be the sum of νk and Fk for at least one of the light sources, and taking fk to be the difference between νk and Fk for at least one other of the light sources. A detector detects the intensity of transmitted light that transmits through the filter.

摘要： An optical transmission apparatus (100) includes an optical transmitter (200) including an optical modulator (220) and an observation optical modulator (230) that attenuate optical power of input continuous wave light by an electro-absorption effect and output the continuous wave light. The optical modulator (220) performs pulse amplitude modulation on the continuous wave light and outputs the optical signal. The apparatus also includes: a bias voltage generation unit (350) that generates a direct-current bias voltage and outputs the direct-current bias voltage to the optical modulator (220) and the observation optical modulator (230); a modulation signal generation unit (360) that generates an electrical signal for pulse amplitude modulation and outputs the electrical signal to the optical modulator (220); and a bias voltage control unit (340) that instructs the bias voltage generation unit (350) to adjust the direct-current bias voltage on the basis of an absorption amount of optical power in the optical modulator (220) and an absorption amount of optical power in the observation optical modulator (230).

摘要： An optical transmitter includes an equalizer which receives a data signal, an optical modulator driver which amplifies an output signal of the equalizer, and an optical modulator which converts an output signal of the optical modulator driver into an optical signal and outputs the optical signal. The equalizer has a signal line for transmitting the data signal, a coupled line electromagnetically coupled to the signal line, a resistive section connected to the coupled line, and a ground via connected to the resistive section. The equalizer reduces power of the data signal in a frequency range where the frequency response characteristic of the optical modulator driver exhibits peaking, to reduce waveform jitter in the output signal of the optical modulator driver that is input to the optical modulator.
