Providing stable and precise optical frequencies with tunable Signals that overcome some of the limitations mentioned above,

Recently, optical modulation has been used to realize OFCG Using a high optical power to induce non-linear effect in the fibers. They use photonic crystal fibers for generating newįrequencies by four-wave mixing (FWM) and Kerr nonlinearity, Lasers and high non-linear optical fibers have also been The environment conditions and the fixed frequency spacing whichĭepends on the cavity length. Unfortunately, this conventional approach has a weak stabilityīecause of the long-length cavity. Of generating a frequency comb is with a mode-locked laser (MLL) Makes it very useful for all these applications. Stability, low noise, low jitter and the fixed frequency spacing which The major advantage of the optical frequency comb is the high Multiplexing (CO-OFDM), metrology and physics research. Over fiber, coherence optical orthogonal frequency-division Optical frequency comb generators (OFCG) can offer manyĪttractive applications such as optical communications, radio Successfully increased as compared with a single laser. Sources and a single-stage Mach-Zehnder modulator. We investigate a wideband optical frequency comb generator based on multi-laser
