Ultra-broadband optical filter based on chirped long-period fiber grating using leaky mode coupling被引量：1
《Optoelectronics Letters》2022年第10期577-582,共6页XUE Linlin Bras Samuel Malumba Timoteo QIU Weiwei WANG Zhongpeng 
supported by the National Natural Science Foundation of China(Nos.61405178 and 61505176);the Zhejiang Provincial Key Natural Science Foundation of China(No.LZ21F010001).
An ultra-broadband optical filter was proposed and demonstrated based on leaky mode coupling in a coated chirped long-period fiber grating(CLPFG). The CLPFG was coated with a material whose refractive index(RI) was hi...
