  • Patent number: 6972620
    Abstract: An optical communication system that includes a multi-channel post amplifier assembly with flexible output configurations for amplifying optical-to-electrical converted signals on selectable groups of amplifier channels is provided. The post amplifier assembly, when implemented on a single IC chip, is capable of operating with either the 2.5V or 3.3V of power supply. In addition, the IC chip containing the post amplifier assembly provides capability to selectively turn off one or more post amplifier channels during operation. Further, the post amplifiers provide integral auto zero function without requiring a use of external capacitors.

  • Patent number: 6919609
    Abstract: An opto-electronic device configured as a photodetector has a capacitor and/or resistor monolithically formed on a surface of the photodetector. The capacitor capacitively couples the AC ground of the photodetector to the bias terminal of the photodetector. The on chip capacitor design eliminates the inductance of external circuit traces between the power supply and an external capacitor. The resistor forces the AC return current of the photodetector through the AC ground in preference to the typical (DC bias terminal) path. Combinations of capacitors and resistors are particularly effective in reducing crosstalk among adjacent detectors in arrays.
