✦ Synopsis

Optical fibers with subwavelength core sizes are shown to offer interesting possibilities for mode birefringence engineering. The Gaussian-mode approximation applied to the analysis of fiber birefringence reveals the existence of a physical limit of form birefringence in an optical fiber, controlled by the trade-off between diffraction and step-index confinement of electromagnetic field in a noncircular waveguiding channel. For fused silica waveguides, a maximum mode birefringence can be achieved in the case of subwavelength core sizes.

We analyze theoretically the evolution of conÿned photonic modes in laterally structured one-dimensional semiconductor microcavities (photonic wires) in a magnetic ÿeld. We show that with the increase of magnetic ÿeld the polarization state of the conÿned photonic modes in photonic wires can be chan

## Abstract An efficient finite‐difference time‐domain method is proposed for the full‐wave analysis of guided modes in photonic crystal fibers. The three‐dimensional hybrid guided modes can be calculated by a two‐dimensional mesh, if one assumes that the propagation constant along the __z__‐direct
