One can achieve perfect impedance matching of dispersive mirrors to the environment over an arbitrarily broad spectral range by tilting the front interface with respect to internal interfaces of the multilayer. As a result, by drawing on this concept one can increase the bandwidth over which the dispersion of the mirrors can be controlled to a full optical octave, limited only by technological constraints (number of layers that can be coated and accuracy of thickness control). Additionally, the undesired fluctuations of the group-delay dispersion as a function of optical frequency are dramatically reduced for tilted-front-interface mirrors compared with conventional chirped mirrors.
