Abstract:
1. A device for processing optical signals, comprising: a first collimator that optically couples an optical signal for processing; one or more optical components that are optically coupled to the first collimator and perform optical processing on the optical signal, wherein at least one optical component has two surfaces, each of the two surfaces including an antireflective coating, at least one of the two surfaces being tilted at an angle from normal with respect to the optical signal so as to reduce chromatic dispersion ripple below what would otherwise result if the two surfaces were normal to the optical signal; and a second collimator optically coupled to the one or more optical components such that the second collimator is able to receive the optical signal from the first collimator and one or more optical components.
