Abstract:
A wavelength dispersion generation apparatus comprising:a virtually imaged phased array (VIPA) generator which receives input light having a respective wavelength within a continuous range of wavelengths and causes multiple reflections of the input light that splits the input light into a plurality of light beams, which produces self-interference of the input light that forms an output light, wherein the output light is spatially distinguishable from an output light formed on input light having any other wavelength within the continuous range of wavelengths; a lens which focuses the output light emitted from said VIPA; and a mirror which reflects the incident light from said lens to return the incident light to said lens, wherein said mirror comprises a multi-faced mirror having multiple reflection surfaces with different shapes in a traveling direction of the incident light from said lens, each of said reflection surfaces reflecting the incident light according to the wavelengths comprising the incident light.
