基于色散调控氟碲酸盐玻璃光纤的O-U波段平坦光频梳产生
O-U Band Flat Optical Frequency Comb Generation Based on Dispersion-controlled Fluorotellurite Glass Fiber
摘要
Abstract
Optical frequency comb(OFC)have great potential in the field of communication as an excellent multi-wavelength light source.By combining OFC light source with wavelength-division-multiplexing(WDM)and space-division-multiplexing(SDM)technologies,the communication system can have a transmission rate in the order of a hundred Tbit/s,which is valuable in 5G/6G communications,Internet of Things,autonomous driving and many other aspects.At present,there are mainly four methods to obtain OFC,which are femtosecond OFC based on mode-locked laser,OFC based on optical microcavity,OFC based on electric-optical modulator and OFC based on travel-ing wave four-wave mixing.All of them have their own characteristics,but all of them are hard to satisfy wide spec-trum,high signal-to-noise ratio,high flatness,high single comb power and wide range adjustable of comb spacing at the same time,which affected the application of OFC in the field of optical communication in some extent.In this pa-per,we put forward to get seed comb from stimulated Brillouin laser cavity,compress the pluse by negative disper-sion highly nonlinear fiber,and further on,widen the spectrum with dispersion-controlled fluorotellurite glass fiber,finally get OFC.The result of numerical simulation shows that,by using this system,we can obtin flat-top OFC with wide range adjustable comb spacing,spectral coverage the hole band form O-U,and the standard deviation of comb power in O-U band less than 5 dB,proved the feasibility of OFC generation based on system with stimulated Brillouin laser cavity and dispersion-controlled fluorotellurite glass fiber.关键词
