Millimeter Wave Optical Link/Frequency Converter System
Abstract
Direct frequency conversion between mmW frequencies and baseband frequencies in the optical domain were validated. The technique utilized a dual wavelength phase locked laser system feeding an external Mach Zehnder modulator. The frequency difference between the two laser lines act as the local oscillator (LO) that up/down converts between baseband frequencies and millimeter wave frequencies. Additional work was performed to examine an alternate conversion technique that would eliminate the radio frequency and LO feed through on the output of the fiber optic link. In addition, the technique could increase the usable dynamic range by allowing more of the current saturating the photodetector to be from the signal and increasing the third order intercept point by 6 dB.
