IPC: G02B6/024
Filed: 1988-12-22
Abstract: PURPOSE:To execute a stable operation without being influenced by an environmental temperature variation and vibration, etc., by separating into two orthogonal polarizations and executing branching or an insertion. CONSTITUTION:In a wavelength multiple signal which is made incident from a first terminal 211 of a first polarization separating element 21, an optical signal of wavelength which is made incident from a first terminal 221 of a second polarization separating element 22 and transmits through an optical filter is inserted into a wavelength group outputted to its fourth terminal 214, and outputted from a fourth terminal 214 of a first polarization separating element 21. In this case, at the time of multiplexing two orthogonal polarizations in a first and a second polarization separating elements 21, 22, an interference effect between the signals to be multiplexed is not used, therefore, a mutual phase relation of signal light beams to be multiplexed exerts no influence on the multiplexing function. In such a way, this element is scarcely influenced by a variation of optical path length caused by a refractive index variation, etc., of a transmission medium of the signal light caused by an environmental temperature variation and vibration, etc., and can execute a stable operation.
