[0003] However, the arrangement of pores in the cladding region of the photonic crystal fiber can greatly affect the mode properties. During normal use, the photonic crystal fiber is often subjected to bending and twisting forces, which makes the pores of the cladding region of the photonic crystal fiber change, thereby Affect the transmission efficiency. In the field of photonic crystal fiber testing, the existing test equipment often simulates that the photonic crystal fiber is affected by a force, but in the actual use process, the photonic crystal fiber is often affected by multiple forces. It is necessary to simulate the photonic crystal fiber under the stress state of the actual use process to test the transmission efficiency of the photonic crystal fiber

The test platform for photonic crystal fiber provided by the present invention includes a simulation workbench and a base, the simulation workbench includes a rotating test module, and a fixing seat and a transmission module are installed on the base; the photonic crystal fiber passes through the fixing seat and the transmission module in turn group, and connected with the rotating end of the rotating test module; the fixing seat is used to fix the photonic crystal fiber; the transmission module is used to form the turning point of bending the photonic crystal fiber, and guide the photonic crystal fiber to the rotating end of the rotating test module ; Fix the photonic crystal fiber through the fixing seat, and drive the rotating test module to rotate, so that the photonic crystal fiber is twisted, thereby simulating the use state of the photonic crystal fiber, and the two ends of the photonic crystal fiber are connected with the test equipment to form a transmission path, so that the obtained True conduction efficiency, the test platform is reliable in structure and easy to use.
Description
technical field [0001] The invention belongs to the field of test equipment, in particular to a test platform for photonic crystal optical fibers. Background technique [0002] Photonic Crystal Fibers (Photonic Crystal Fibers), a type of chalcogenide glass photonic crystal fiber, because the dispersion value of the chalcogenide glass fiber is flat and close to zero, this makes the wavelength of the pulsed seed light source have a wider choice, in optical coherence Tomography, spectrum detection, nonlinear microscopy and other fields have immeasurable application prospects; this type of chalcogenide glass photonic crystal fiber guides the solid core area surrounded by pores. It enables significant flexibility in the dispersed design of PCFs by controlling the core size, pore size and periodicity, [0003] However, the arrangement of pores in the cladding region of the photonic crystal fiber can greatly affect the mode properties. During normal use, the photonic crystal fiber...
