GRATING TYPE OPTICAL COMPONENT AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To miniaturize a gain equalizer for a narrow bandwidth transmission loss-wavelength waveform. SOLUTION: The miniaturized gain equalizer can be realized even if it has a narrow bandwidth transmission loss-wavelength waveform, by developing super-structure long period fiber gratings in which a plurality of gratings having a length L1 and an equal structure are formed via an unformed part of gratings mutually having a length L2, and providing this unformed part of gratings with the long period fiber gratings.
