| 英文摘要 | PURPOSE:To realize a tunable integrated type wavelength filter having constitution, in which the intensity of signal light to the light of a background can be increased, and constitution, in which the generation of noises by spontaneous emitted light can be suppressed. CONSTITUTION:Tunable wavelength filters 5, 5', 6 and wavelength selective couplers as directional couplers 1, 2, 3:1, 2', 4 mounted on at least one of the upstream side and downstream side of the filters are integrated in series, and coupled optically. A DFB/DBR type tunable wavelength filter is used as the filter, and two wavelength selective couplers for removing spontaneous emitted light are arranged in series while sandwiching the filters between. |
