摘要： A light transmitting apparatus of the invention includes: a light transmitting section having a light source and an EA modulator, and a control section that controls the optical output power of the light transmitting section to be constant, based on a monitor value of EA photoelectric current. The control section uses a reference value corresponding to a wavelength of the light source, from amongst reference values of the EA photoelectric current that are different for each wavelength, and feedback controls the light transmitting section depending on a difference between the reference value and the monitor value. As a result it is possible to reliably suppress fluctuations in the optical output power due to changes in the wavelength of the light source.

摘要： In an optical transmission apparatus, a light-emitting laser varies its output wavelength when applied with a wavelength control signal for switching wavelengths. A wavelength controller outputs the wavelength control signal, and a filter unit subjects the wavelength control signal to a filtering process to remove high-frequency noise superimposed on the wavelength control signal. The filter unit stops the filtering process during the wavelength control and executes the filtering process during the operation.

摘要： A wavelength locker includes: a birefringent plate for separating light emitted from a light source into two beams of light which are approximately in parallel to each other; a first light receiving element for directly receiving one of the two beams of light separated by the birefringent plate; a λ/4 plate and an etalon filter through which other one of the two beams of light separated by the birefringent plate passes; and a second light receiving element for receiving the other one of the two beams of light which has passed through the etalon filter. The λ/4 plate has an optic axis tilted at 45 degrees with respect to a polarization direction of light incident on the λ/4 plate, changes a polarization direction of light, which has been reflected by the etalon filter and incident on the λ/4 plate, such that the reflected light does not return to the light source after passing through the birefringent plate, and emits the resultant light.

摘要： A wavelength-variable light source generates light having a wavelength according to an input wavelength control current. An EA modulator modulates light generated by the wavelength-variable light source, based on a modulation characteristic corresponding to an input EA bias. A TEC changes the temperature of the wavelength-variable light source and that of the EA modulator according to an input temperature control current. A control unit adjusts the setting-value of the wavelength control current input to the wavelength-variable light source, the setting-value of the EA bias input to the EA modulator, and the setting-value of the temperature of the EA modulator according to input wavelength data.
