Abstract

The invention relates to the filed of optical fiber communication and fiber laser, and particularly to a swept laser based on optical fluid. The swept laser based on the optical fluid comprises the components of a pump light source, a fiber wavelength division multiplexing device, an Er-doped fiber and a spectrum analyzer. The pump light source is connected with the fiber wavelength division multiplexing device. The output end of the fiber wavelength division multiplexing device is connected with the spectrum analyzer. The common end of the fiber wavelength division multiplexing device is welded with the Er-doped fiber. The end of the Er-doped fiber is cut to be flat and is fixed on a horizontal fiber clamp. The horizontal fiber clamp is fixed on a high-precision linear translation stage. The optical fluid is plated on the tail fiber of the flat cut Er-doped fiber.

Description

technical field [0001] The invention relates to the field of optical fiber communication and optical fiber laser, in particular to a frequency-sweeping laser based on optical fluid. Background technique [0002] In the optical transmission system, frequency-swept lasers can generate periodic wavelength-tuned output, and are widely used in fiber grating demodulators and optical coherence technology. The core components of frequency-swept lasers are tunable filters, such as acousto-optic filters, Fab Re-Perot (F-P) filter, the existing frequency-sweeping laser generally uses semiconductor optical amplifier (SOA) as the gain medium, and the output of frequency-sweeping light mainly relies on tunable filters, and these filters have high At the same time, using SOA as a gain medium also increases the cost of the entire frequency-swept laser. For example, the patent "High-Speed ​​Broadband Narrow Linewidth Sweeping All-Fiber Laser" (application number 201310638343.6) uses a large...
