Abstract: In a method and an optical switch by which a signal light is accurately switched even if a polarization state of a signal light inputted has a fluctuation, power of an output light of a polarizer which receives a signal light extracted from an output light of a nonlinear optical medium is monitored and a polarization state of an input signal light to the nonlinear optical medium is controlled so that the power becomes minimum (or maximum). The polarization state of the input signal light is monitored, a calculation of performing a predetermined conversion is executed to the polarization state of the input signal light, and a calculated polarization state is recorded (or recorded without conversion). A polarization state of a control light with respect to the input signal light is monitored and the polarization state of the control light is controlled so as to coincide with the polarization state of the input signal light recorded.

Abstract: A polarimeter and polarimetry method are disclosed of the type in which light polarization rotating properties of a sample are measured by interposing the sample in the path of a light beam having base plane polarization in a plane of known orientation; along the beam path, compensating or nulling the rotation introduced by the sample, and determining the optical rotational properties of the sample based on the amount of compensation introduced to the light beam. In accordance with one aspect of the present invention, the light beam is subjected to plural compensations along its path the compensations being of at least two different types. Preferably, one of the types of compensation is mechanical, introduced through a device in which polarization rotation is adjusted mechanically, and the second type of compensation is provided through a device in which polarization rotation is controlled electrically. In accordance with another aspect of the invention, a first polarization rotation compensation is performed with the sample in the beam path, the sample is removed, and compensation is restored by performing a second polarization rotation compensation, the second compensation being used to determine the polarization rotation introduced by the sample.

Abstract: A method and device capable of evaluating the specific values of the polarization state of the signal transmitted in a photonic transmission system for a number of frequencies of one or more of the pulses extracted from the optical signal by means of the translation of the frequential components of polarization state of one or more pulses to the time domain by means of the use of an optical Fourier transformer, and their sampling, quantification and subsequent analysis.From the analysis the variation in the polarization state versus frequency is calculated, as well as its associate PMD vector and the DGD present in the signal transmitted. This information may be used as a control signal for a PMD compensator device in order to upgrade the quality of communication in the system.
