Light-propagation and imaging in planar optical waveguides
Bend losses can be understood as coupling to non-guided and thus lossy modes. From inside the book. The basic idea of coupled-mode theory is to decompose all propagating light into the known modes of the undisturbed device, and then to calculate how these modes are coupled with each other by some additional influence.
Strong resonant coupling can occur in certain situations, involving frequency degeneracies of resonator modes. A 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.
Account Options Sign in. Mode Coupling The concept of mode coupling is very often used e. The field evolution has been calculated with numerical beam propagation, and the local mode powers have been obtained from the results using overlap integrals with the mode functions as obtained from a mode solver applied to the bare fiber. The book is a completely new survey of the most recent advances in the areas of integrated optics and optelectronics.

Technically, the mode coupling approach is often used in the form of coupled differential equations for the complex excitation amplitudes of all the involved modes.
Some examples of mode coupling are discussed in the following: Evolution of mode powers in a long-period fiber Bragg grating, which couples light from the injected fundamental mode radiation into higher-order modes. This approach is often technically and conceptually much more convenient than, e.

Sorry, we don’t have an article for that keyword! This method is computationally more intense, but can generate more detailed insight. References to this book Encyclopedia of Optical Engineering: If the fiber is strongly bent, this can introduce coupling e.

Las-Pho, pages Ronald G. Express 19 11 In addition, it will serve as a comprehensive reference manual for the theory and application of the most recent thin-film optical and optoelectronic technology. My library Help Advanced Book Search. Included are sections on basic theory as well as detailed descriptions of fabrication technology, applications and a plethora of available devices. For example, aberrations of the thermal lens in the gain medium of a solid-state bulk laser couple the modes of the laser resonatoras calculated without these aberrations.
This mechanism can kogelnil either a Kramers—Kronig effect or thermal distortions influencing the refractive index profile. An important physical aspect of such coherent mode coupling phenomena is that the optical power transferred between two modes depends on the amplitudes which are already in both modes.

This diagram has been taken from a case study on beam propagation in fiber devices. Because of the systematic arrangement of its chapters, the book should also be very useful to graduate and senior undergraduate students.

An optical fiber may have several propagation modes, to be calculated for the fiber being kept straight. Bertoni Snippet view – Encyclopedia of Optical Engineering: In this situation, however, not all involved modes are necessarily resonant at the same time.
