Abstract:
An optical switch for manipulating a plurality of input optical signals incident thereupon to split one or more optical signal channels from the plurality of input optical signals. The optical switch includes an optical filter having a first reflective region and a second reflective region. One of the first and the second reflective regions is adapted with a wavelength selective filter that is capable of separating one or more optical signal channels from the input optical signal. A translating mechanism cooperates with the optical filter and is adapted to translate the optical filter in a plane substantially parallel to one of the first reflective region and the second reflective region between a first position and a second position. The translation of the optical filter causes at least one of the one or more optical signal channels to be separated from the optical signal and directed in a second direction. Additionally, another of the one or more optical signal channels to be separated from the optical signal can be directed in a third direction.
Abstract:
The device (10) includes multiple layers of different materials including at least one plastic substrate layer (16) having a dye material for absorbing IR energy emission and which is preferably color correcting, and an optically selective coating (22) providing a high photopic transmittance, continuous high electrical conductivity for RFI shielding and reflectivity within the near-IR region. The device (10) may include antireflective coating (28, 26), and the dye material for absorbing IR energy emission may constitute an IR absorbing coating (not shown).
