title: Generalized grating equation for virtually-imaged phased-array spectral dispersers.
abstract: The virtually-imaged phased array (VIPA) is a side-entrance etalon with potential application as a high-resolution spectral disperser for wavelength division multiplexing. Here we present an approximate analytical spectral dispersion law for the VIPA, which we confirm experimentally.
