Modeling of coupling coefficient as a function of coupling ratio [PDF]

SPIE Proceedings, 2008
Coupled 1X2 Single Mode Fiber (SMF-28e"R") has been successfully fabricated using a slightly unstable torch flame at a temperature range of 800°C to 1350°C injecting hydrogen gas flowing at pressure of 1 bar. The coupling ratio and coupling coefficient can be examined from 1% until 75%.

Defining the coupling coefficient for electrodynamic transducers

The Journal of the Acoustical Society of America, 2013
This paper provides a simple, practical definition of the coupling coefficient for electrodynamic transducers. Comparing to efforts made in previous works that assumed a lossless spring-inductor model, the definition presented here is based on a lossy mass-inductor model. Time-harmonic analysis is used to model the energy flow in the transducer.

Coupling coefficient of gain-guided lasers

Applied Optics, 1984
An analytical model is presented for the coupling coefficient for two gain-guided coupled waveguides, e.g., semiconductor laser arrays. A common parabolic gain distribution is assumed for the lasers, and the effective dielectric constant distribution is approximated in terms of the bulk refraction index, wavelength, power filling factor, and the ...

Coupling coefficients of coupled laser cavities

IEEE Journal of Quantum Electronics, 1986
We discuss certain properties of the coupling coefficients for a specific model consisting of two coupled resonant cavities separated by a lossy coupling gap. The coupling coefficients are here defined in the framework of time-dependent coupled-cavity theory-not as end-fire power coupling between traveling waves of two adjacent waveguides.

Coupling coefficient in strongly coupled dielectric waveguides

Radio Science, 1977
The coupling properties between two strongly coupled parallel dielectric slab waveguides are investigated using an analytical method based on waveguide theory. Coupling properties between two waveguides which have different geometrical configurations are given.

The impact of laterally coupled grating microstructure on effective coupling coefficients

Nanotechnology, 2010
Lithographic fabrication may be used to define laterally coupled gratings of high refractive index contrast on waveguide ridges, eliminating the need for regrowth steps in such distributed feedback lasers. These may be made more amenable to fabrication by employing higher-order gratings.

Dynamic multi-coupling coefficients

Journal of Physics A: Mathematical and General, 2000
Summary: Exact eigen-energies and the corresponding wavefunctions of an interacting \(\text{sl}\)-boson system in a \(\text{U}(2l + 1)\leftrightarrow \text{O}(2l+2)\) transitional region are obtained by using the Bethe ansatz within an infinite-dimensional Lie algebra. A numerical algorithm for solving the Bethe ansatz equations is introduced.
