Abstract
A two-part article is presented describing a highly stable computer-controlled K-B and frequency synthesizer using a tunable optoelectronics oscillator (OEO). The first part describes LabVIEW control of a rack-mountable frequency synthesizer covering 16 to 24 GHz. A narrowband computer-controlled filter is realized using a broadband YIG filter combined with a narrowband, optically-tuned transversal filter. A forced self-injection locked phase-locked loop (SILPLL) technique is employed to suppress side-modes generated in OEOs because of long fiber delay lines, which reduces the oscillator phase noise to an estimated 12 fs timing jitter. Computer control of this SILPLL OEO is demonstrated with linear chirp (FMCVV) and pseudo-random frequency hopping. Future generations of the forced SILPLL OEO will use integrated optoelectronics. In Part 2 of the article, compact OEO solutions based on designs compatible with Si photonics are described.
