Abstract
LPFGs written by high-frequency CO2 laser pulses have great potential for use in optical fiber sensing and communication. It is of importance to study the fundamental characteristics of these novel LPFGs. In this paper, a more systematic analysis is carried out to investigate the resonant wavelength-bend sensitivity of the LPFG and its bend loss of resonant peaks based on the mode field theory. It is for the first time to our knowledge, that a method is proposed for analysis of the bend orientation-dependence of the LPFG. The simulation is in agreement with experimental results. This paper provides a more systematic analysis for the bending characteristics analysis of the LPFG written by the high-frequency CO2 laser pulses exposure method.
