Ultra-low-stress thin-film interference filters.
A method to reduce the optical degrading effect of coating stress in a thin-film filter by releasing the filter from the substrate on which it was deposited is described. An extremely challenging 8-skip-0 100 GHz wavelength-division-multiplexing band-splitting filter is demonstrated.
