Experiment and Analysis System without Modulation Locked Fiber Grating System

Abstract:

High stability of semiconductor lasers have been shown useful in many applications areas,^[such as optical communication, high-resolution spectroscopy quantum metrology, laser cooling and trapping^[. With the rapid development of fiber optic dense wavelength division multiplexing system, we require laser source with high frequency stability in 1.5μm band. In this paper It is clear that temperature, cavity length and injection current have effects on frequency stability of FBG external cavity semiconductor laser by simulation experiments. Besides that, the frequency stabilization system is adjusted. Therefore, the frequency jitter spectra before and after locking are given and the experimental results are analyzed. The results show that after locking laser the typical frequency jitter is significantly improved comparing with frequency fluctuation in the condition of free running.
