J. Marti et al., Millimeter-wave signal generation and harmonic upconversion through PM-IM conversion in chirped fiber gratings, FIBER IN OP, 19(2), 2000, pp. 187-198
A novel technique for generating millimeter-wave signals through phase-to-i
ntensity modulation conversion in chirped fiber gratings is proposed and de
monstrated Experimental results on generating a 28 GHz signal using harmoni
es orders from 7th to 10th are provided. Excellent phase-noise performance
(-87 dBc / Hz @ 10KHz) is demonstrated. It is also demonstrated that this t
echnique may be efficiently used for harmonically upconverting intermediate
frequency signals to the millimeter-wave band Bit-error-rate measurements
far different modulation format (QPSK/MQAM) signals, which were upconverted
employing the PM-IM conversion technique, show very good performance (< 10
(-9)) and transparency to the modulation format.
