摘要： A semiconductor optical amplifier (10) is utilized for optical amplification and for detection of an optical signal (12) at the current injection electrode (14) of the optical amplifier (10). A wide detection bandwidth is provided by utilizing an impedance transformer (26) between the current injection terminal (22) and the detection circuit (28). The impedance transformer (26) typically has an input impedance of about 1 to 15 ohms. The impedance transformer (26) can be a bipolar junction transistor circuit, a microstrip transmission line impedance transformer or a hybrid impedance transformer. A wide detection bandwidth is also obtained by providing a semiconductor optical amplifier (10) having two current injection electrodes. A bias current (20) is supplied through both current injection electrodes, and both electrodes produce optical gain. However, only one of the electrodes is used for optical signal detection. The detection electrode has a relatively high junction resistance and a relatively high series resistance.

摘要： An optical communication system (Figs. 1-4, 6-7) which includes an optical transmitter (Fig. 1) for transmitting an optical signal through a single-mode optical fiber (22, 88) to an optical receiver (Figs. 3, 9, 10). The optical transmitter includes an optical source for generating a light beam. The optical source is preferably a high speed laser diode (20, 86) emitting in a spectral range of 1.3 - 1.6 micrometers. The light beam is intensity modulated with a composite modulation signal comprising one or more modulated microwave subcarriers and a baseband digital signal. The microwave subcarriers are typically in the frequency range between 2 and 20 gigahertz, and the baseband digital signal is typically a time-multiplexed signal carrying multiple voice and data channels. By simultaneously transmitting a baseband digital signal and multiple microwave subcarriers on a single optical fiber, the information-carrying capacity of the optical communication system is increased.
