HIGHLY STABILIZED MILLIMETER-WAVE GENERATION BY USING FIBEROPTIC FREQUENCY-TUNABLE COMB GENERATOR

A novel optical generation and transport technique for millimeter-wave (mm-wave) signal by using the fiber-optic frequency-tunable comb gene rator having a discrete emission spectrum as the light source is propo sed. 60 GHz mm-wave signal generation and transmission over 108 km-lon g optical fiber link at lambda = 1560 nm is demonstrated. Excellent st ability of both the frequency and amplitude of the mm-wave carrier is attained that the 3 dB linewidth is less than 0.3 kHz and the variance of the amplitude fluctuation is 0.07 dB, The advantages include a tun ability of the carrier frequency, handling ease, and no need of high-s peed external light modulator.
