摘要： 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.

摘要： A small-size optical rotation measuring device for detecting an organism, a tissue, blood, or molecules having rotatory power and determining the content thereof with high accuracy and an optical rotation measuring method for detecting an organism, a tissue, blood, or molecules having rotatory power and determining the content thereof with high accuracy. A nonreciprocal optical system is disposed in a loop optical path of a ring optical interferometer, and thereby light beams of circularly polarized modes orthogonal to each other are propagated in opposite directions through a sample to be measured. The wavelength of the light beams from a light source is in a wavelength region where the loss by the nonreciprocal optical element is low. A signal processing technique for phase-modulation optical fiber gyro having the highest resolution among ring interferometers is applied.
