摘要： A modulator arrangement comprises two Mach-Zehnder modulators, a main modulator (2) and a compensation modulator (3) having non-linear transmission functions. The modulators (2, 3) are controlled by a modulating control signal (V), via electrodes (16, 17). A carrier wave (S1) from a laser (7) is power divided (a, 1-a) into part-waves in a power divider (5) between the modulators (2, 3). The modulated part-waves (S2, S3) are superimposed at an output (14) to produce a resultant modulated wave (S4). A linearized transmission function between the control voltage (V) and the power of the resultant modulated wave (S4) has a radius of curvature whose length is maximized within a control voltge range, so as to minimize intermodulation distortion. The mean slope of the transmission function is maximized within this range. At a common control voltage (V) for the modulators (2, 3), the modulator arrangement has an optimal transmission function at a length ratio b = √3:1 between the modulators (2, 3), and a power ratio between the part-waves of √3 :9. The main modulator (2) is the shortest and modulates the strongest part-wave.

摘要： A terahertz optomechanical transducer for transducing an incident electromagnetic wave (3) having a terahertz frequency within a terahertz frequency band of use. The terahertz optomechanical transducer comprises an electromagnetic resonator (1) having a response bandwidth including said frequency. The electromagnetic resonator (1) comprises a first element (2) and an opposite element (4) forming with the first element a capacitive gap. The first element is mechanically configured to response to the action of an force stemming (7) from an electric field generated by interaction of said incident electromagnetic wave with electric charges present in said electromagnetic resonator. The electric field is generated between a first electric pole (6) induced in said first element (2) by first electric charges having a first electrical sign and a second electric pole (5) induced in said opposite element (4) by second electric charges having a second electrical sign opposite to the first electrical sign. The first electric charges and the second electric charges alternate between the first and the second electric poles (5, 6) in time at the terahertz frequency of the incident electromagnetic wave.
