Abstract
A microwave fiber optic link is developed for operation from 8 to 18 GHz. Modulation of a 1.3-μm wavelength optical carrier is accomplished using a lithium niobate Mach-Zehnder interferometer modulator that was designed for broadband operation up to 19 GHz. The link transmitter components, which consist of a high-power semiconductor laser, an optical isolator, and a modulator with polarization-preserving fiber pigtails, are spliced together to fit into a 10.16- x 5.08- x 2.54-cm3 (4- x 2- x 1-in.) box for applications where space is critical. The average link electrical gain is 45 dB, the frequency response is flat to within ±4 dB across the 10-GHz band, and the spur-free dynamic range of the link is 84 dB.
