摘要：
A continuous phase-only sampling scheme enabling one to create an ultrahigh-channel-count fiber Bragg grating (FBG) with excellent channel uniformity and high in-band energy efficiency is proposed that is based on the simultaneous utilization of two phase-only sampling functions. With this method, a linearly chirped 135-channel FBG with a length of 10 cm, a dispersion of 1360 ps/nm, channel spacing of 0.8 nm, and grating strength of 10 dB is theoretically demonstrated, and the maximum refractive index change required is less than 10(-3).
