    摘要： In an optical modulator according to the invention, with respect to two MZ type optical modulators connected to each other in tandem by a curved folded waveguide on an identical substrate, a longitudinal direction of an MZ type optical waveguide unit on an optical input port side is obliquely arranged to a longitudinal direction of an MZ type optical waveguide unit on an optical output port side, and a curvature radius of the curved folded waveguide is made larger than a half of an interval between the optical input/output ports to decrease a length of a feeder portion of a signal electrode corresponding to the MZ type optical waveguide unit on the input side. Therefore, a loss of an electric signal propagated through the signal electrode can be reduced.

    摘要： In the bias stabilization control using average optical power of signal light, there is a case where a control algorithm (maximum control or minimum control) changes depending on the amplitude of clock voltage, or it becomes out of control. In an optical modulation device for performing CSRZ optical modulation on outgoing light from an optical source, control light inputted from a control light input path is inputted into an LN-MZ optical modulator having traveling-wave type modulating electrodes from a direction opposite to signal light, and the average optical power is detected by a photodetector. A bias-voltage Vb is so generated that this optical power may be minimized, and is applied to a bias input terminal, whereby automatic bias stabilization control is performed.

    摘要： Traveling-wave optoelectronic wavelength conversion is provided by a monolithic optoelectronic integrated circuit that includes an interconnected traveling-wave photodetector and traveling-wave optical modulator with a widely tunable laser source. Either parallel and series connections between the photodetector and modulator may be used. An input signal modulated onto a first optical wavelength develops a traveling wave voltage on transmission line electrodes of the traveling-wave photodetector, and this voltage is coupled via an interconnecting transmission line of the same characteristic impedance to transmission line electrodes of the traveling-wave optical modulator to modulate the signal onto a second optical wavelength derived from the tunable laser. The traveling wave voltage is terminated in a load resistor having the same characteristic impedance as the photodetector and modulator transmission lines. However, the interconnecting transmission lines and the load resistor may have different impedances than the photodetector and modulator.
