  • Publication number: 20100220376
    Abstract: An optical modulator and an optical transmission system convert continuous light of a multiple wavelength light source, which generates the continuous light with a fixed and complete phase but different frequencies, to a modulator driving signal so as to generate a light subcarrier with each frequency at the center and modulate the continuous light to the light subcarrier by using the modulator driving signal. In the case where an optical modulation is carried out by an optical IQ-modulator, transmitting data, for example, is converted to two parallel data A(t) and B(t), an I phase signal, in which the data A(t)+B(t) are modulated with a clock signal with a frequency ?, and a Q phase signal, in which the data A(t)?B(t) are modulated with a clock signal with a ?/2 phase shifted, are generated, and the I phase signal and the Q phase signal are applied to electrodes of the optical IQ-modulator, respectively.

  • Publication number: 20090309864
    Abstract: A first driving circuit alternately reverses polarities of voltages applied to a first and a second electrode in order to cause sustain discharge between the first and second electrodes. A second driving circuit applies a pulse to a fourth electrode in synchronization with a timing when the Polarities of the voltages to the first and second electrodes are reversed. Further, during the sustain discharge, the second driving circuit keeps a voltage of the fourth electrode after the application of the pulse, at an offset voltage deviated by a Predetermined value from an initial voltage that the fourth electrode has before the generation of the pulse, and thereafter returns the voltage of the fourth electrode to the initial voltage. For example, the offset voltage is set to a value between a high-level voltage and a low-level voltage applied to the first and second electrodes. Consequently, luminescent efficiency can be improved.
