Paper Abstract

The dynamic range ofwideband microwave externally modulated fiber optic transmission systems is limited by the power handling ability ofthe photodetectors used in the receivers. External modulators can be designed to reduce the optical carrier of the output by using a branch structure to split offsome ofthe input optical carrier, and coherently reduce the optical carrier at the output. A number ofdesign issues relating to modulator fabrication and bias point control result from these approaches. Keywords: optical carrier suppression, external modulator, SFDR, photodiode power handling, fiber optic links
