An intuitive analytical interpretation of the generated diffraction orders is proposed for gratings with linear variation of the period and linear variation of the spatial frequency. Also, experiments using Gaussian beams and plane wave illumination are performed. The analytical expressions are compared to numerical and experimental results, showing a high agreement. Chirped gratings can be implemented in interesting applications: we analyze how they can be used as a deflector, since tunable direction of diffracted orders can be achieved by displacing laterally the grating with respect to the incident light beam. Also the angular width of diffraction orders can be controlled and chirped gratings can be used to generate uniform illumination over a controlled angular range. These two applications have also been experimentally shown. 000130250 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/RTC-2016-5277-5 000130250 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000130250 590__ $$a3.319$$b2018 000130250 591__ $$aOPTICS$$b21 / 95 = 0.221$$c2018$$dQ1$$eT1 000130250 591__ $$aPHYSICS, APPLIED$$b38 / 148 = 0.257$$c2018$$dQ2$$eT1 000130250 592__ $$a0.775$$b2018 000130250 593__ $$aAtomic and Molecular Physics, and Optics$$c2018$$dQ1 000130250 593__ $$aElectronic, Optical and Magnetic Materials$$c2018$$dQ1 000130250 593__ $$aElectrical and Electronic Engineering$$c2018$$dQ1 000130250 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000130250 700__ $$0(orcid)0000-0003-3178-5253$$aTorcal-Milla, Francisco Jose$$uUniversidad de Zaragoza 000130250 700__ $$aBuencuerpo, Jeronimo 000130250 7102_ $$12002$$2385$$aUniversidad de Zaragoza$$bDpto.
