OPTICAL RECEIVER

摘要

An optical receiver includes an antireflection coated laser preamplification stage(2). The laser amplifier provides a signal above the sensitivity of a low impedance amplifier, and therefore it is not necessary to use a high sensitivity amplifier. Avoidance of a high sensitivity amplifier enables a greater bandwidth to be achieved. The arrangement provides extended bandwidth performance at high bit rates over state of the art devices, and at low bit rates provides comparable performance with economical structure.
