摘要： A high-frequency signal from a tape-shaped line section having a surface layer signal lead and surface layer GND lead disposed on both sides thereof is directly inputted to a semiconductor chip via a signal surface layer wiring of a package substrate and through solder bump electrodes. Alternatively, a high-frequency signal from the semiconductor chip is outputted to the outside via the tape-shaped line section in reverse. Owing to the transmission of the high-frequency signal by only a microstrip line at the whole surface layer of the package substrate, the high-frequency signal can be transmitted by only the microstrip line at the surface layer without through vias or the like. Accordingly, the high-frequency signal can be transmitted without a loss in frequency characteristic, and a high-quality high-frequency signal can be transmitted with a reduction in loss at high-frequency transmission.

摘要： Included are: a gain chip having a gain unit and a phase control region; a current supply for causing a positive current to flow to the phase control region; a voltage supply for applying a bias voltage to the phase control region; and a control unit for selectively driving the current supply or the voltage supply depending on a direction of the wavelength shift. The control unit drives the current supply when a laser wavelength is to be shifted to a shorter wavelength side from a wavelength with the current supply and the voltage supply being turned off, and drives the voltage supply when the laser wavelength is to be shifted to a longer wavelength side from a wavelength with the current supply and the voltage supply being turned off.
