Las-Pho, pages Ronald G. The concept of mode coupling is very often used e. This leads to a strong loss of beam quality above a certain pump power level.

Express 19 11[13] A. Encyclopedia … combined with a great Buyer’s Guide! Sorry, we waaveguides have an article for that keyword! This diagram has been taken from a case study on beam propagation in fiber devices.

Express 19 11 Written by nine authors who are internationally recognized authorities in their areas, the book contains chapters on optical waveguides, lightwave junctions and other thin-film components, lithium-niobate LiNbO3 devices, guided-mode semiconductor GaAs and related lasers and integrated optic devices. In this way, mode B is prevented from acquiring sufficient power to extract power from mode A efficiently, so that mode A experiences only little loss, despite the coupling.


Contents Introduction By T Tamir. Guided-wave optoelectronics Volume 26 of Springer series in electronics and photonics. Nonlinear interactions in a waveguide can also couple the modes as calculated for low light intensities to each other. This approach is often technically and conceptually much more convenient than, e.

For some cases with statistical variations of coupling effects, one may use a coupled-power theory instead of standard theories based on amplitude coupling [11]. Express 14 13[10] M. If you like this article, share it with your friends and colleagues, e. Waveguidess consequence of that is that the power transfer from a mode A to another mode B can be kept very small simply by strongly attenuating mode B.

This mechanism can involve either a Kramers—Kronig effect or thermal distortions influencing the refractive index profile. Bertoni Snippet view – This picture can serve e. Fiber Bragg gratings FBGs can be understood is fibers which are equipped with additional means for mode coupling — for example, for reflecting light with short period gratings or for coupling to modes guided modes or cladding modes wafeguides in the same direction with long period gratings.


Strong resonant coupling can occur in certain situations, involving frequency degeneracies of resonator modes.

The book should be of great interest to all researchers and engineers involved with integrated optics, optoelectronics and electro-optic systems and devices. Encyclopedia of Optical Engineering: My library Help Advanced Book Search.

Account Options Sign in. This method is computationally more intense, but can generate more detailed insight. B 58, Waveguide Transitions and Junctions. The book is a completely new survey of the most recent advances in the areas of integrated optics and optelectronics.

This nonresonant nature of the coupling means that the coupling will in general have a small effect — which is essential for laser operation with high beam qualitysince otherwise wvaeguides would strongly excite higher-order modes, having a higher beam parameter product. An optical fiber may have several propagation modes, to be calculated for the fiber being kept straight.
