Abstract
An optical device which comprises at least one first passive or active element and an integrated grating arrangement. The device furthermore comprises a tuning device for controlling and changing the angle of incidence of a beam incident to the grating arrangement. The tuning device comprises a variable index prism arranged between said first active or passive element and the grating arrangement.
