PURPOSE:To provide a multiplex separation coupling circuit capable of providing a wavelength multiplex separation coupling circuit without using plural branching circuits and in which the increment of the number of components can be suppressed. CONSTITUTION:This circuit contains a transmission side collimator array 10 to input wavelength multiplex optical signals from plural ports, a wavelength filter array 20 on which plural wavelength filters which transmit one of wavelength components of emitted light and reflect others and with different transmission wavelength components are arranged, a total reflection plane mirror 30 arranged in parallel with the wavelength filter array 20, a luminous flux re-arranging element 40 which inverts the spatial arrangement of collimated light which transmits the wavelength filter array 20 and its progressive direction, and a reception side collimator array 50 which converges wavelength multiplex signal light individually and transmits it to the plural ports. |
