High-Frequency Modulation and Fiber-Optic Links for Phased Arrays
Abstract
Direct modulation and detection studies were performed using various laser diodes from 2 to 22 GHz. A LiNbO3 traveling wave Mach-Zehnder interferometer was used for external modulation. The modulated beams were coupled into an optical fiber, demodulated by fast detectors, and spectrum analyzed. Attempts were also made to obtain higher order harmonics after direct modulation of the laser diodes by making use of the nonlinear behavior of the lasers. However, very high frequencies beyond K band could not be detected because of the limitations of the detectors. Keywords include: High-frequency modulation, Fiber optics, Direct modulation, External modulation, Laser diodes, Detectors, Phased array.
