They can extend the lifetime of plasmonic excitations, enabling the operation nanolasers, or they can increase the fluorescence of quantum emitters. They also provide control over nonlinear optical processes such as second harmonic generation and four-wave mixing. Fano resonances can both enhance or suppress nonlinear response. Interference of two or more absorption\/conversion paths is responsible for the appearance of these effects. In this \u003ci\u003eChapter\u003c\/i\u003e, we demonstrate explicitly -on a single equation- how path interference takes part in linear and nonlinear Fano resonances.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eKeywords\u003c\/b\u003e\u003ci\u003e: L\u003c\/i\u003e\u003c\/p\u003eifetime, second harmonic generation, four-wave mixing \u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003ci\u003e \u003c\/i\u003e\u003c\/p\u003e\u003cp\u003e2.

Additional non-conservative functions are thus required for deriving spin observables, such as circular dichroism or magneto-optical effects. In this chapter, a conservative approach for achieving optical spin will be described, by exploiting Fano spectral-separation of optical spins. Starting from spinor temporal coupled mode theory for 2D\/3D chiral resonances, the origin of spin-Fano interactions is demonstrated: the link\u003c\/p\u003e between spinor eigenvectors in the polarization domain and anti-symmetric Fano resonances in the spectral domain. Compared with chiral, gyrotropic, and birefringent materials, novel applications of this spin-Fano resonance are discussed toward optical spintronics: including highly-selective spin switching and unpolarized operations.\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eKeywords: \u003c\/b\u003e\u003ci\u003eoptical spin, anti-symmetric Fano resonance, optical spintronics\u003c\/i\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e3.

The Fano resonances observed in micro and nano optical systems have received particular attention due to their numerous potential applications like in sensing, switching, lasing, filters and robust color display, nonlinear and slow-light devices, invisibility cloaking, and so forth. Most of the aforementioned applications are known to critically depend upon the ability to control or modulate the asymmetry of the spectral line shape by external means. Thus, tuning the Fano resonance via some experimentally accessible parameters are highly desirable for realistic applications. In this chapter, we discuss a new concept based on polarization Mueller matrix analysis for tuning the Fano interference effect and the resulting asymmetric spectral line shape in anisotropic optical system. The approach is founded on a generalized model of anisotropic Fano resonance and exploits the different polarization response (anisotropy) of the two interfering modes to achieve un\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Eugene Kamenetskii\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3319997300\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783319997308\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Springer\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/01\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 582\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 2.25lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 1.31d","brand":"Eugene Kamenetskii","offers":[{"title":"Hardcover","offer_id":44073604972799,"sku":"9783319997308","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_a6c8f3e5-1477-4a38-b8d0-533096b05ac3.jpg?v=1685448811","url":"https:\/\/www.whiterainbookhouse.com\/products\/fano-resonances-in-optics-and-eugene-kamenetskii-9783319997308","provider":"WR Book House","version":"1.0","type":"link"}
