摘要： The invention relates to a device for detecting the PMD of optoelectronic transmission lines. The inventive device is characterized in that it comprises a narrow-band, tuneable laser, whose illumination is superimposed with the illumination of the transmission line to be analysed and an optoelectronic heterodyne receiver which receives the superimposed signal.

摘要： A method, a system and a computer program product configured to determine a differential group delay of two sequential optical beams based on a frequency dependence of a length of an optical path traveled by the two sequential optical beams in a dispersion compensating grating (60). The determined differential group delay provides a measure of polarization mode dispersion in the dispersion compensation grating (60).

摘要： A first tunable wavelength pulse light source (22) is driven by a reference signal to emit a first optical pulse. An optical demultiplexer (24) demultiplexes a first optical pulse emitted from the first pulse light source (22) into a reference optical pulse and an incident optical pulse to be sent into an object to be measured. An optical multiplexer (26) multiplexes the reference optical pulse and an outgoing optical pulse passing through the object to output multiplexed light. A second pulse light source (23) generates a second optical pulse which is synchronous with the first optical pulse and delays a predetermined time for each period of the first optical pulse. A sampling unit (27, 27a, 27b) receives the multiplexed light and the second optical pulse to obtain an optical pulse train signal proportional to the intensity of the multiplexed light obtained in synchronism with the second optical pulse. From the optical pulse train signal from the sampling unit (27, 27a, 27b), a signal processor (37) obtains an envelope formed by peaks of individual optical pulses forming the optical pulse train. The wavelength dispersion of the object is obtained by measuring the delay time of the outgoing optical pulse passing through the object on the basis of intervals between the peaks of the envelope.

摘要： A method and an apparatus for determination of properties, e.g. of elements of the Jones matrix of an optical device under test, comprising the steps of: producing an incoming light beam, splitting the light beam into a first light beam and a second light beam, coupling the first light beam, preferably having two parts delayed with respect to each other, with a given initial polarization into the optical device under test, letting the second light beam travel a different path than the first light beam, superimposing the first light beam and the second light beam to produce interference between the first light beam and the second light beam in a resulting superimposed light beam, splitting the superimposed light beam into a third light beam polarization dependent and a fourth light beam, detecting the power of the third and the fourth light beam as a function of frequency when tuning the frequency of the incoming light beam over a given frequency range, deriving optical properties, e.g. elements of the Jones matrix, from the frequency dependency of the detected power.

摘要： A method and a device for compensating the polarization mode dispersion (PMD) of a transmitted optical signal comprise means of a polarization controller (3) coupled to a differential group delay (DGD) generator (5). The polarization controller (3) is controlled by a feedback loop, said feedback loop implementing an optimisation algorithm to optimize a feedback parameter of the output signal of the DGD generator (5). The algorithm takes into account the state of polarization (SOP) of an optical signal determined from the output signal of the polarization controller (3) ) or from the output signal from the DGD generator (5).
