Title: Interference film type optical branching filter
Inventor: SUGIMOTO SHIGETOKI
IPC: G02B6/34
Filed: 1980-01-09
Abstract: PURPOSE:To provide a branching filter which is small in size, is economical and is good in environment resistance by providing at least five light input and output terminals on the focal plane of two lenses, and coupling at least two of these terminals wit an optical coupler. CONSTITUTION:When the waveform-multiplexed light of 2 channels enters an optical input terminal T22, it enters an interference film filter F3 through a lens L21.  The light of one wavelength is mostly reflected and reaches the terminal T21, and  the light of the other wavelength transmits through the filter F3, is condensed at a light input terminal T23, and emits from a terminal T24 by passing through the optical coupler C2. When it again enters the interference film filter F3, this component receives considerable attenuation as compared to the initial component; therefore, only the one component is transmitted to the terminal T25. Namely, the transmission characteristics of the light emitting from the light output terminal T25 by passing through the interference film type branching filter 30 are improved by using just one branching filter 30, in the manner similar to that when two of them are used.
