Abstract
- Abstract: A triple sampling method to have enabled excellent channel uniformity and high in-band energy efficiency is firstly proposed for the design of an ultrahigh-channel-count fiber Bragg grating (FBG), which is based on the simultaneous utilization of two amplitude-assisted phase sampling (AAPS) functions and a phase-only sampling (POS) function. As an example, one linearly chirped FBG with consecutive 1215 channels enabling to cover all fiber telecom bands (O+E+S+C+L+U) is numerically demonstrated, which has a length of 9cm, a dispersion of −1360ps/nm, and a channel spacing of 50GHz. The maximum index-change required for 10dB strength of the FBG is less than 6×10−3. [Copyright &y& Elsevier]
