“…Guidance is assured by total internal reflection coming from the smaller volume average refractive index of the cladding compared to that of the core [16]. Directional coupling in symmetric dual-core devices has been investigated previously both theoretically [17][18][19][20] and experimentally [21,22], with applications including polarization splitting [19,20] and super-broadband directional coupling [18]. The asymmetric mode-selective coupler presented in this paper shares similar broadband characteristics, whilst permitting directional coupling between different modes.…”

Directional mode coupling in an asymmetric holey fiber coupler is demonstrated both numerically and experimentally for the first time. The holey fiber mode couplers have interesting spectral characteristics and are also found to exhibit increased dimensional tolerances. Following a design based on numerical investigations, a dual-core polymer holey fiber coupler for LP 01 and LP 11 mode multiplexing was fabricated via a drilling and drawing technique. The measurements are compared with the simulation results.

Photonic crystal fibers are a new class of optical fibers. Their artificial crystal-like microstructure results in a number of unusual properties. They can guide light not only through a well-known total internal reflection mechanism but using also photonic bandgap effect. In this paper different properties possible to obtain in photonic crystal fibers are reviewed. Fabrication and modeling methods are also discussed.

“…10 In recent years, couplers based on PCFs have attracted people's attention since the PCF coupler was experimentally investigated by Mangan et al 11 Compared with conventional couplers, very short coupling length and other new features can be realized by changing the structural dimensions of PCF couplers. Furthermore, optical passive components based on PCF couplers, such as polarization splitters 12,13 and wavelength splitters, 14 were also designed and investigated. However, for common PCFs or PCF couplers, the inherent polarization mode coupling and polarization mode dispersion will deteriorate the performance of systems in certain polarization-sensitive applications like fiber optic gyroscopes and high-power fiber lasers.…”

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.
