    摘要： An optical integrated circuit comprises a semiconductor body, a semiconductor optical waveguide located on the body, and a bipolar phototransistor located on and optically coupled to the waveguide. In a preferred embodiment, the base region of the transistor is configured to absorb radiation propagating in the waveguide, but the emitter and collector regions are both configured not to absorb the propagating radiation. In a further preferred embodiment, the waveguide is configured to guide the radiation along a propagation axis therein, and the transistor makes an elongated footprint along the waveguide, the footprint being elongated along the direction of the propagation axis. In another preferred embodiment, the footprint is at least three times longer along the propagation axis than along a direction perpendicular thereto.

    摘要： A feedforward linearizer includes a signal cancellation circuit and an error cancellation circuit. The signal cancellation circuit includes a tap delay line, that delay the input signal by a predetermined time delay so as to provide several delayed versions of the input signal. Each delayed version of the input signal is weighted by a tap coefficient. The weighted signals are then added together and fed to the power amplifier. The tap coefficients are derived such that the signals traveling through the upper and lower branch of the signal cancellation loop are aligned and that the output signal of the power amplifier is equalized.
