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 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.

Modeling coupled microchip lasers requires complex coupling coefficients

Journal of the Optical Society of America B, 2000
Two coupled microlasers display instabilities in the intermediate regime between locked and independent states of oscillations. The frequencies and amplitudes of these oscillations exhibit strongly asymmetric behaviors for positive and negative detunings.

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.

Determination of electrokinetic coupling coefficients

SEG Technical Program Expanded Abstracts 2005, 2005
Electrokinetic coupling can convert an electromagnetic wave into a seismic wave or a seismic wave into an electromagnetic wave and is the basis of a new exploration method called Coupled Waves (Thompson and Gist (1993 and 1999), Hornbostel and Thompson (2002), Hornbostel, et al. (2003), and Ross et al. (2005)).

Coupling coefficients: General theory

Journal of Mathematical Physics, 1979
Coupling coefficients for projective representations of finite groups are determined quite generally either by means of a general projection procedure, or as a linear combination of their corresponding Clebsch–Gordan coefficients. There we demonstrate that coupling— and Clebsch–Gordan coefficients are uniquely connected by special Clebsch–Gordan ...

Rate coefficients in reacting strongly coupled plasmas

Physical Review A, 1988
A kinetic approach is derived to take into account nonideality effects in the rate coefficients of plasmas. First results are given for a reacting hydrogen plasma.

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.

Corrugated Grating Coupled Devices and Coupling Coefficients

Integrated Optics, 1976
Marcuse has used local normal mode theory to calculate general expressions for the coupling coefficients (distributed leakage - DL and distributed feedback - DFB) for asymmetric slab waveguides with corrugated core boundaries.1 This approach and in general most approaches to this problem2,3,4 do not give one much feeling for the workings of the ...

Mode coupling coefficient measurements in optical fibers

Applied Optics, 1978
The measuring method of the mode coupling coefficient was developed to apply to multimode fibers. It is shown that a mode coupling coefficient can be calculated from each mode group pulse waveform. Measurements were made with two cases of long-length and short-length multimode step-index fibers.
