We compare a simple dynamical model of fiber laser arrays with independent experiments on two coupled lasers. The degree of agreement with experimental observations is excellent. Collectively the evidence presented supports this dynamical approach as an alternative to the traditional static eigenmode analysis of the coupled laser cavities.

A mode-evolution-based polarization splitter suitable for high-index-contrast systems and directly integratable with a recently reported on-polarization rotator is described and its performance verified through both finite-difference time-domain and eigenmode expansion simulations. For a device length of 200 microm, greater than 22 dB of extinction is obtained across a 1.45-1.75-microm bandwidth.

After having previously demonstrated the occurrence of ageostrophic, anticyclonic instability (AAI) for several other steady flows, in this paper we further test the hypothesis that rotating, stably stratified, shear flows are generally subject to AAI at finite Rossby (Ro) and Froude (Fr) numbers by calculating the inviscid, incompressible normal modes of a geostrophic, barotropic boundary curr...

Geometrical chirality is a universal property encountered on very different length scales ranging from geometrical shapes of living organisms to drug and DNA molecules. The interaction chiral matter with light, that is, an electromagnetic field possessing certain handedness, underlies our ability discriminate enantiomers In this context, it often desired have optical cavity efficiently couples ...

For the wireless communication systems coupled with multiple transmit receive antennas and orthogonal frequency-division multiplexing (OFDM), data sub-streams can be directed along orthogonal modes of channels, when spatial channel information is known at transmitters. These eigenmodes are generally obtained by the singular value decomposition (SVD) of spatial channel fading matrix at every car...

This paper presents a formulation of two-dimensional straight photonic crystal waveguide consisting of circular cylinder array in triangular lattice. The fields are expressed in the generalized Fourier series expansions but we also use the cylindrical-wave expansions. The present formulation is derived by the technique for multilayer with infinite thickness. key words: photonic crystal waveguid...
