Abstrakt:

The development of 6G wireless networks aims to provide high-speed, low-latency communication, with millimeter-wave frequencies (from 30 to 300 GHz) crucial for enabling high-capacity communication. These frequencies offer significant bandwidth but present challenges in signal generation and processing. A promising solution is the use of supercontinuum (SC) generated in highly nonlinear fibers (HNLF), the nonlinear optical process which creates broad spectral outputs spanning multiple frequency bands. HNLFs, with their high nonlinearity and dispersion properties, facilitate wideband optical spectra when subjected to high-intensity pulses. In this study, we explore supercontinuum generation using a semiconductor optical amplifier (SOA) to produce high-intensity pulses at 1550 nm, injected into a 4-meter-long HNLF. The proposed system generates a supercontinuum spectrum with average power of 31 dBm and peak pulse width of 0.008 ps, spanning from 1529 nm to over 1570 nm. The SOA in the ring cavity is optimized to generate supercontinuum without needing an external laser or pump source. The HNLF output is then detected by a photodetector to produce millimeter-wave signals. The system generates signals over a 1 GHz–5 THz range, with an output power of 39.9 dBm at 30 GHz, making it self-sustaining without an external laser.
