Photonic crystal mirrors for high-resolving power fabry perots
A Fabry-Perot cavity comprised of three-dimensional photonic crystal structures is disclosed. The self-assembly of purified and highly monodispersed microspheres is one approach to the successful operation of the device for creating highly ordered colloidal crystal coatings of high structural and optical quality. Such colloidal crystal film mirrors offer high reflection with low losses in the spectral window of the photonic band gap that permit Fabry-Perot resonators to be constructed with high resolving power, for example, greater than 1000 or sharp fringes that are spectrally narrower than 1.0 nm. The three-dimensional photonic crystals that constitute the Fabry-Perot invention are not restricted to any one fabrication method, and may include self-assembly of colloids, layer-by-layer lithographic construction, inversion, and laser holography. Such photonic crystal Fabry-Perot resonators offer the same benefits of high reflection and narrow spectral band responses available from the use of multi-layer dielectric coatings. However, the open structure of three-dimensional photonic crystal films affords the unique ability for external media to access the critical reflection layers and dramatically alter the Fabry-Perot spectrum, and provide means for crafting novel laser, sensor, and nonlinear optical devices. This open structure enables the penetration of gas and liquid substances, or entrainment of nano-particles or biological analytes in gases and liquids, to create subtle changes to the colloidal mirror responses that manifest in strong spectral responses in reflection and transmission of the collective Fabry Perot response.

The production methodcomprises the following steps: (1) performing coating, namely according to layout designing requirements of partial transfer paper, manufacturing a special edition coating anilox roller, and partially coating a PET (polyethylene terephthalate) base membrane by a transfer coating; (2) performing mold pressing, namely performing mold pressing on laser holography anti-fake information on a mold pressing machine, wherein holography information is mold-pressed in an area coated by the transfer coating, and an area without the transfer coating is not provided with the holography information; (3) performing aluminum plating, namely performing aluminum plating according to a normal laser holography aluminum plating process, enabling an aluminum layer to adhere to the coating in the area coated bythe transfer coating, and enabling an aluminum layer to adhere to the PET base membrane in the area without the transfer coating; and (4) performing combining peeling, namely smearing a transfer adhesive in a whole edition on a combining machine to combine an aluminum layer surface of the laser holography partial transfer membrane with paper, and peeling off the PET base membrane, so as to obtainpartial transfer paper. The edge of the partial transfer paper obtained by using the method is tidy, and the packaging molding speed can be greatly increased, that is, is up to 800 pieces of paper / minute at most.
