Abstract
A wavelength-multiplexed fiber optic link architecture has been designed for transmitting ri signals with wide instantaneous band width and LO signals at microwave frequencies over long distances. The architecture involves downconverting the input rf signal, directly amplitude modulating a laser diode, transmitting the resulting rf-modulated optical carrier through single-mode fiber, and subsequently up-converting the recovered rf signal to the original band. Wavelength division multiplexing and demultiplexing is used to transmit the local oscillator signal (required for down- and up-conversions) from the transmitter to the receiver through the same fiber. By using a frequency-divided LO signal in conjunction with frequency multipliers, the wideband rf signal can be down/up-conveiled anywhere in the rf spectrum up to 100 GHz. A demonstration link has been implemented using this architecture and operates from 6.3 to 16 GHz. This link uses a 1.3-μm, 10-GHz rf bandwidth laser diode for IF transmission and a 1.55-μm, 1.5-GHz rf bandwidth laser diode for LO transmission.
