“…The cladding effective index is assumed to be the index of fundamental space-filling mode that can be obtained by applying FEM to an elementary piece of the cladding. 14,15 It is well known that only the mode whose effective index is larger than that of the cladding can be guided in the core, and therefore, the cutoff of each supermode takes place at the intersection points between the cladding index line and the corresponding supermode index line. We can see in Fig.…”

Abstract. A single-polarization single-mode (SPSM) photonic crystal fiber (PCF) coupler is designed and investigated by using full-vector finite-element method with the anisotropic perfectly matched layer. We numerically analyze the SPSM coupling properties with respect to the structure parameters and confinement loss characteristics. The results reveal that the coupling length between dual cores is as small as millimeter order of magnitude due to the wide silica bridge of energy transfer, and the SPSM coupling region can be tailored to cover the communication windows of 1.3 or 1.55 μm with optimized design parameters. Moreover, the confinement loss of x polarization is 3 orders of magnitude larger than that of y polarization in single polarization range. The proposed SPSM PCF coupler may find application in polarization-sensitive systems. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…1,14 The ability of suppressing one polarization fundamental mode in single-polarization single-mode (SPSM) PCFs or PCF couplers makes them good candidates for polarization-sensitive occasions. In our previous work, the investigation of SPSM PCFs has been carried out 15 and therefore, this paper focuses on the SPSM PCF coupler.…”
