A cartridge-type optical functional module achieves excellent optical coupling and may include an optical fiber-type module and/or a waveguide-type module. A cartridge-type optical functional module is provided that includes first and second optical fiber collimators, an optical functional object that has an optical fiber-type module or a waveguide-type module, and a base section. The optical functional object also includes a third collimator, and a first alignment mechanism for aligning the position of the third collimator in the optical functional object.

A wavelength selective polarization controller capable of controlling the polarization plane of optical wavelength multiplexing signals, for each wavelength component, and which does not generate time lag between each component is provided. This wavelength selective polarization controller has: a telecentric optical system to which optical wavelength multiplexing signals are incident; a polarization controller that controls the polarization plane of light output from the telecentric optical system; and an output optical system for outputting to an optical path output from the polarization controller. The telecentric optical system has: a first diffraction grating to which the optical wavelength multiplexing signals are incident; and a first condenser that condenses the optical wavelength multiplexing signals that have passed through the diffraction grating. The polarization controller has a plurality of phase modulators.
