摘要： The present invention relates to a pulse modulation method and the like having a structure for effectively suppressing nonlinear optical phenomena which increase as an optical pulse becomes wider when amplifying the optical pulse with a predetermined period as seed light. A modulator performs pulse modulation for a laser light source which is a seed light source or light outputted from the laser light source. A modulation pattern of a modulated voltage outputted from the modulator is adjusted such as to include a plurality of pulse components each having a signal width shorter than the pulse width of the optical pulse as an optical pulse generation pattern within a modulation period corresponding to a period of the optical pulse.

摘要： The present invention relates to an optical module having a structure for reducing adverse contingencies such as increased number of fusion splicing points, drops in output, and higher costs associated with a greater number of optical components. The optical module comprises an amplification optical fiber, a transmission optical fiber, and a fusion splicing structure that fusion-splices the amplification optical fiber to the transmission optical fiber, in a state where a cover layer is removed at the tip portions, including the end faces, of these optical fibers. The fusion splicing structure includes a pumping light removing resin that covers directly the tip portions of the amplification optical fiber and the transmission optical fiber from which the cover layer is removed. The pumping light removing resin has a higher refractive index than a first cladding of the amplification optical fiber. The above configuration allows transmitted pumping light, for which the confinement effect by the first cladding of the amplification optical fiber is cancelled, to escape more efficiently out of the fusion splicing portion.

摘要： The present invention relates to an optical module that has a structure for protecting a pumping light source at a low cost. The optical module comprises an amplification optical fiber, an optical coupler, a pumping light source, a delay optical fiber, a seed light source, an optical fiber, a photodetector, an optical fiber, an optical isolator, an optical isolator, and a control section. Through the insertion of the delay optical fiber between the pumping light source and the optical coupler, the timing of the output control of the pumping light source which is carried out after the photodetector detects return light leads the timing with which the return light enters the pumping light source. Hence, the time with which the return light enters the pumping light source is shortened and the accumulative damage time of the pumping light source is reduced.

摘要： The present invention relates to an optical amplifier with a structure for more effectively suppressing the over/undershoot in transient responses in high-speed AGC. This optical amplifier is an optical device for amplifying signal light inputted therein, and comprises a rare-earth-element-doped optical fiber, an optical coupler, a light-receiving section, a pumping light source, and a control section. In particular, as a typical structure of the optical amplifier, the rare-earth-element-doped optical fiber has a cutoff wavelength λc set longer than the pumping light wavelength λp but shorter than the signal light wavelength λs, and mainly allows a pumping light component in a fundamental mode to propagate therethrough. The pumping light and signal light are made incident on the first rare-earth-element-doped optical fiber such that only the pumping light component in the fundamental mode and a signal light component in the fundamental mode propagate through the first rare-earth-element-doped optical fiber in a state where the first rare-earth-element-doped optical fiber extends straight.
