    Abstract: A light modulation device capable of stabilizing a phase set in phase modulation processing and improving optical communication quality. A phase modulator is provided for each of plural branched input lights and performs phase modulation of the input light. A phase shifter is provided at the upstream or downstream of the phase modulator and shifts a phase of the input light or of the phase-modulated light. A light interference section causes the output lights from the light modulator to interfere with each other to generate a multilevel phase modulated signal and interference light having a phase state different from that of the modulated signal. A monitor receives the interference light and outputs an electric signal according to the intensity. A phase shift controller generates a phase control signal based on the electric signal and applies the signal to the shifter to control the phase shift amount to be set by the shifter.

    Abstract: A signal detecting apparatus detects a signal received based on a current received and includes a detecting unit that detects, in the current received, a peak equal to or higher than a threshold and a time counting unit that counts a given period of time from a point in time of detection of the peak by the detecting unit. The signal detecting apparatus further includes a determining unit that determines whether the detecting unit has detected the peak again within the given period of time counted by the time counting unit. An output unit of the signal detecting apparatus outputs information indicating detection of the signal received when the determining unit determines that the peak has been detected again.

    Abstract: An amplifying unit performs a differential amplification with a highest level or a lowest level of an input signal and a previous input signal. A semiconductor element transfers a signal level output from the amplifying unit from a second terminal to a third terminal by using a current conducted from the second terminal to the third terminal in response to a voltage applied to a first terminal. A control unit controls the voltage applied to the first terminal of the semiconductor element based on a voltage or a current related to a reference semiconductor element. A holding unit holds a signal level output from the third terminal of the semiconductor element.

    Abstract: A signal amplification device which uses inexpensive standard CMOS and yet is capable of high-accuracy threshold setting. An offset voltage generator detects the direct-current level of an input signal, and generates a positive or negative offset voltage signal. A peak detector outputs, as a peak value, the positive offset voltage signal if the level thereof is higher than the maximum level of the input signal, or the maximum level of the input signal if the maximum level is higher than the positive offset voltage signal. A bottom detector outputs, as a bottom value, the negative offset voltage signal if the level thereof is lower than the minimum level of the input signal, or the minimum level of the input signal if the minimum level is lower than the negative offset voltage signal. A voltage divider subjects the peak and bottom values to voltage division, to generate a threshold level.
