Supercontinuum fiber light sources with their extremely wide wavelength spectrum can provide new options for achieving specific wavelength distributions in a very flexible way. Two concepts for the combination of such supercontinuum light sources with a spectrally dispersive optical system and an interactive filter for modulating the light spectrum are discussed. These concepts provide the possibility...
Based on Berreman's 4×4 matrix formalism [W. Berreman, J. Opt. Soc. Am. 62, 502 (1972)] we derive simplified expressions for the reflection formulas from the a–c crystal surface for non-normal incidence. The computational effort to apply the formulas was found to be only insignificantly higher than those for normal incidence, but considerably lower than for the general expressions. Consequently, the...
