For planar-integrated free-space optical (PIFSO) systems high-reflectance thin-film coatings are crucial. Evaporated metal films are preferred for their relative technological simplicity. We propose a three-layer Al-Ag-Al coating composition that combines the high reflectance of Ag with the chemical passivity of Al and its good adherence to glass. Two special measures are taken to prevent delamination: one is an anchoring of the edges of the coating in narrow ditches that are etched into the…

Practical realization of reflective metallic coatings for planar-integrated free-space optics ( PIFSO )
In planar-integrated free-space optics (PIFSO) [1] the systems approach of which is shown schematically in Abb.1 signals may have to bounce up and down a considerable number of times inside a planar…

Progress in the development of a durable silver-based high-reflectance coating for astronomical telescopes.
TLDR
Silver-based high-reflectance coatings that can withstand the humid and polluted conditions common in the open air have been developed for astronomical telescope optics and have improved durability, which is due to the copper underlayer.
Planar Integration Of Free-Space Optical Components
In complex optical systems comprising many individual components, the alignment of these components becomes a severe problem, especially if the alignment tolerances are in the micron or submicron…
Multichip module with planar-integrated free-space optical vector-matrix-type interconnects.
TLDR
The planar integration of free-space optics into a photonic microsystems engineering concept has been optimized for the given geometrical and technological constraints and provides a good interconnection performance, as was verified in computer simulations on the basis of ray tracing and in practical experiments.
Practical realization of massively parallel fiber-free-space optical interconnects.
TLDR
This work proposes a novel approach to realizing massively parallel optical interconnects based on commercially available multifiber ribbons with MT-type connectors and custom-designed planar-integrated free-space components, which proves that multiple one-to-one and one- to-many interConnects can be established with not more than 10% uniformity error.
Planar-Integrated Free-Space Optics: From Components to Systems
TLDR
This chapter aims at providing an overview of the development of PIFSO, characterized by a shift from component-related design and fabrication issues to system- and application-related ones.

Optical properties of the metals Al, Co, Cu, Au, Fe, Pb, Ni, Pd, Pt, Ag, Ti, and W in the infrared and far infrared.
TLDR
The data for the noble metals and Al, Pb, and W can be reasonably fit using the Drude model and it is shown that -epsilon1(omegas) = epsilon2(omega) approximately omega(2)(p)/(2omega( 2)(tau) at the damping frequency omega = omega(tau), where the plasma frequency is omega(p).
