摘要： PROBLEM TO BE SOLVED: To sample optical signals with a simple and low cost configuration and high sampling efficiency, and to stably acquire waveform information of high speed optical signals. SOLUTION: Sampling is made as follows. A carbon nanotube element 23 is used as a sampling element of an optical sampling device 22. An optical signal Px to be monitored is made incident into one optical terminal 23a thereof, and a sampling optical pulse Ps emitted from an optical pulse generator 21 for a sampling pulse is made incident into the other optical terminal 23b of the carbon nanotube element 23 through an optical coupler 25 to lower an absorption ratio to the optical signal Px by supersaturated absorption properties generated when the sampling optical pulse Ps is made incident, and to emit the optical signal from the other optical terminal 23b.

摘要： PROBLEM TO BE SOLVED: To prevent an excessive output which can occur when the setting of an optical band pass filter is changed, related to an optical amplification device comprising an APC function and an optical band pass filter. SOLUTION: A controlling method is disclosed for an optical amplification device wherein an input light is amplified, a light of optical band pass region set to an optical filter among amplified light is extracted, and the output light is adjusted to a specified level based on the extracted light. In order to change the optical band pass region set to the optical filter, the level of output light is suppressed. Then, a new optical band pass region is set to the optical filter. Further, the output light is set to a specified level.

摘要： PROBLEM TO BE SOLVED: To sample optical signals with high sampling efficiency with simple low-cost constitution and to stably obtain waveform information of high-speed optical signals.
SOLUTION: A carbon nanotube 23 is used as a sampling element of an optical sampling device 22, and the optical signal Px to be monitored is made incident to one optical terminal 23a. Sampling optical pulse Ps emitted from an optical pulse generator 21 for sampling pulse is made incident to the other optical terminal 23b of the carbon nanotube element 23 through an optical coupler 25, and an absorption factor to the optical signal Px is lowered by supersaturated absorption characteristics generated at the incidence of the sampling optical pulse Ps to carry out emission from the other optical terminal 23b for sampling.
