Design of fiber optic rotary joint based on photonic crystal fiber
Fiber optic rotary joint is used for signal transmission between stationary platform and rotary platform because of its advantages of high bandwidth,electromagnetic compatibility,small size,etc. A novel design of fiber optic rotary joint based on direct coupling technology of large mode area photonic crystal fiber(LMA-PCF)is designed. The analysis results of coupling theory indicate that this design provides low insertion loss and decrease requirement of accuracy of machining and assembly. Because LMA-PCF possesses the properties of non-cut-off-wavelength single-mode and lower non-linear transmission,the PCF optic rotary joint could be effectively associated with technology of WDM to increase transmission capacity.
