Summary: | This paper reports a low phase noise single-loop optoelectronic oscillator (OEO) using Er-Yb codoped fiber amplifier (EYDFA). Its performance is compared with Erbium-Doped Fiber Amplifier (EDFA) in terms of the Quality factor (Q), phase noise, and eye diagrams. The opti-system simulation confirms 36.14 Q-factor and -149.08 dBc/Hz phase noise at 10 kHz offset frequency with Er-Yb codoped fiber amplifier. Also, the reliability study is performed using different fiber loop lengths to determine the optimized OEO design. The proposed OEO generates a 10 GHz microwave signal with low-frequency drift along a 5 km optical fiber loop, which is suitable for X-band radar applications. |
