Paper Abstract

A high-sensitivity, wide-bandwidth, optical preamplifier is demonstrated in the form of a monolithically integrated semiconductor optical amplifier and waveguide photodetector. By fabricating the same device with a shorter photodetector section, part of the signal is passed through to an output fiber, forming an optical tap. Amplifier gains are sufficient to overcome the fiber-coupling and detector loss, and exhibit zero-insertion-loss operation. A lossless tap with an electrical bandwidth of 7 GHz, a responsivity of 26 A/W, and a fiber-to-fiber gain of 3 dB is shown to have a receiver sensitivity of -22 dBm at 3 Gb/s.
