摘要： An arrangement and a method are disclosed for compensating for distortion in an optical signal having data modulated thereon which was caused by distortion effects on an optical fiber link, using a dispersion compensator which processes the incoming optical signal such that an optical or electric signal having the data of the input signal modulated thereon is provided at its output, with the output signal of the dispersion compensator exhibiting a distortion reduced from that of the input signal. The arrangement and the method are characterized in that the dispersion compensator is preceded by an optical bandpass filter which limits the spectral range of the incoming optical signal to a narrower range. In this way, even optical signal distortion due to higher-order dispersion effects can be selectively compensated for with simple technical means such that greater link lengths and more reliable adaptation to varying transmission conditions become possible.

摘要： An optical time multiplexer for generating an N Gbits/s output signal (36) from n data modulated input pulse streams (21, 22) with a pulse frequency of N/n GHz, where nnullIN and nnull2, with a combiner device for passively interleaving the n input pulse streams (21, 22) is characterized by at least nnull1 first phase shifting elements (25) tuning the optical phases of at least nnull1 input pulse streams (22) and being connected to a controller device (32), which derives at least nnull1 control signals from a comparison of the optical phases of the n input pulse streams (21, 22) and controls the at least nnull1 first phase shifting elements (25) such that the optical phases of all n input pulse streams (21, 22) are locked with respect to each other. This optical time multuplexer reduces the drifting penalty of ODTM signals due to multiplexer instability, it prohibits the broadening of RZ pulses, and it grants the possibility to easily generate carrier-suppressed RZ signals or similar modulation formats.

摘要： A device for adjusting the polarization of an incoming optical signal with a polarization divider (1), a first phase setter (3) in the signal path of at least one of the two output signals from the polarization divider, a first optical coupler (4), a second phase setter (5) in the signal path of at least one of the two output signals from the first optical coupler, and with a second optical coupler (6), an actuating signal being supplied to the phase setters respectively in a feedback loop, said actuating signal being obtained from a quality signal derived from the processed optical signal, is characterized in that a substraction element (10) is provided, to which the two parallel optical signals are supplied from a point after the first optical coupler, a bipolar quality signal being obtained in the substraction element from the difference of the two signals supplied, and that a control element (11) is connected downstream of the substraction element, which control element generates an actuating signal to one of the phase setters that adjusts this such that the amount of the quality signal is minimized and in particular adjusted to zero. This makes it possible for just a single related quality signal to be used for each manipulated variable, and for optimization to be effected by a search for a minimum signal or a balance instead of a maximum search, for the quality signals used to be bipolar, for the appropriate adjusting method to be executed more quickly and simply without complicated sweeping of the manipulated variables and for an inexpensive control logic to be used for the feedback.

摘要： An inclusion of the liquid crystal in the direct vicinity of the core of an optical waveguide structured on a substrate allows to build a tunable optical device. The liquid crystal will be confined by replacing cladding material of that integrated structure. The tuning of the property of that liquid crystal i.e. its refractive index will influence directly the mode index of the core. This influence can be of such amount to allow to control the flow of optical signals transmitted through it. The tuning is advantageously achieved by applying some electric field via electrode on a segment of that core confined with liquid crystals.
