Holographic polarization-selective and wavelength-selective elements in optical network a

摘要

Abstract: Volume-type holographic optical elements perform polarization-dependent characteristics, and highly polarization-selective holographic elements can be achieved with suitable designs. In addition, wavelength-selective characteristics can also be designed with volume-type holographic optical elements. These polarization-selective and wavelength-selective components have been designed and fabricated in various structures. In this presentation, we first review the basic structures of our holographic polarization-selective and wavelength-selective elements. Normally incident and output coupling of our compact and light-weight components provide better flexibility and easier alignment for system applications. Based on these holographic optical elements, we will introduce the compact structures for various optical interconnect applications.!23
