On-chip waveguide resonator with metallic mirrors

Optics Letters, 2010
We introduce an optical microresonator consisting of a planar waveguide terminated by metallic mirrors. The resonator was fabricated on a silicon-on-insulator platform, and its optical performance was theoretically and experimentally investigated. The demonstrated device had dimensions of 200 mumx40 mum and exhibited a quality factor of about 1000 and ...

Metal Hydride Switchable Mirrors (Review)

Optics and Spectroscopy, 2020
At the end of the 20th century, the phenomenon of optical properties changing from mirror metal to transparent upon hydrogenation of thin films of some chromogenic materials was discovered. Such devices were called “switchable mirror.” The amazing properties of the new materials and the possibility of creating smart windows on their basis have caused ...

Metal Mirrors in the Large

Optical Engineering, 1975
The state of the art in manufacturing large one piece metal mirrors has advanced dramatically in the past 10 years, following important pioneer work by NASA's Jet Propulsion Laboratory in 1965. Since that time, several additional large solar simulator mirrors have been manufactured.

Ion beam smoothing of metallic mirrors

Materials Science and Engineering, 1987
Abstract The implantation of 150 keV molybdenum ions into molybdenum mirrors and 400 keV silver or copper ions into copper mirrors is found to increase the reflectivity of these mirrors. Analysis of ellipsometric data from these samples using the Bruggeman effective medium approximation demonstrates that the change is due to smoothing of the surface.

Metal buffer layer inserted switchable mirrors

Solar Energy Materials and Solar Cells, 2008
Thin buffer layers of hydrogen diffusive metals such as Ti, Nb, and V were inserted between a Mg4Ni thin film and a Pd top layer, which were prepared by DC magnetron sputtering. Their optical, electrochemical properties, and switching durability were investigated using both gasochromic and electrochromic switching methods.

Design and Mounting of Metallic Mirrors

2018
The discussion in this chapter begins in Section 10.2 with some general considerations of metal mirrors as distinguished from nonmetallic ones. A variety of examples of metal mirror design and fabrication techniques are then discussed. Mirrors made of various materials are considered in Sections 10.3 through 10.5.

Residual infrared absorption in metal mirrors

Soviet Journal of Quantum Electronics, 1988
An analysis is made of the physical factors that limit the reflectivity of mirrors in the infrared range. It is shown that the mechanism responsible for the finite residual absorption is the electron–phonon interaction in the presence of a photon (Holstein–Gurzhi effect).

Lapping metal mirror at high speed

SPIE Proceedings, 2000
This paper discusses lapping a metal mirror with solid abrasives at high speed. In this method there are three procedures. First the workpiece is ground in a grinding machine, which makes the surface roughness of the workpiece reach about Ra1.6micrometers .
