Paper Abstract

It has been known for sometime that the tap angles associated with slanted, tilted and blazed Bragg grating structures can be affected by the guided mode's state of polarization (SOP). Recently this polarization dependent out-coupling has been employed in order to develop a number of useful devices including in-line polarimeters and PDL equalizers. Although a variety of tools are available to model blazed fibre Bragg grating (FBG) characteristics, a simplified explanation of the fundamental dependencies and potential behaviour has never been fully presented in the literature, making the optimization of these devices difficult and elusive at times. In this submission we present a thorough, intuitive discussion of these trends and possibilities as observed through an extensive theoretical analysis rooted in the Volume Current Method (VCM). In addition to discussing the potential limitations and shortcomings of this formulation, some rough guidelines for the manufacture of various devices are also disclosed.
