Ultra-Efficient Silicon-on-Insulator Grating Couplers With Backside Metal Mirrors
IEEE Journal of Selected Topics in Quantum Electronics, 2020Coupling of light from off-chip into highly complex silicon-based devices is currently focus of efforts and research. In this work, the experimental demonstration of a −0.50 dB (89%) coupling efficiency in the C-band with the help of an aperiodic grating

Additive manufacturing of metal mirrors for TMA telescope
Optical Systems Design, 2018Additive manufacturing enables enhanced designs for metal mirrors and housings of optical systems like telescopes. Internal lightweight structures are used for the mirror modules to reduce the weight of the system while keeping the mechanical stability ...

Polishing of supersmooth metal mirrors
Applied Optics, 1975This work has resulted in clarifying the fabrication technology that is required for high energy 10.6-microm laser programs now underway. Polishing and coating techniques for metallic substrates were developed, and the deposition of metallic coatings to reproducibly create metal mirror surfaces with low absorptance at a wavelength of 10.6 microm was ...

Abstract Several pertinent parameters are frequently overlooked in specifying metal mirrors for high energy laser systems. This report outlines the importance of those parameters and describes both the typical and the state-of-the-art characteristics presently available.

Terahertz reflectivities of metal-coated mirrors
Applied Optics, 2011Terahertz (THz) reflectivities of a variety of metal-coated mirrors were measured. Gold, silver, and aluminum coatings were tested and compared. It was found that all types of optical metal-coated mirrors perform equally well as THz reflectors.

In recent years, metal mirrors have grown in popularity. Many short courses and papers have discussed the mechanical properties and calculated rigidity and thermal performance of mirrors. This presentation will briefly touch on these but give more emphasize on metal mirror fabrication procedures, material comparisons, and cost.

Polariton trap in microcavities with metallic mirrors
Journal of Physics: Condensed Matter, 2011In planar microcavities with metallic mirrors the spectra of cavity polaritons may be strongly modified by the presence of a surface plasmon interacting with transverse-magnetic (TM)-polarized cavity modes. In particular, for certain parameters of the cavity, a minimum in the dispersion of the TM-polarized polariton may develop, which is located in the
