Embodiment 1

[0053] Made such as Figure 5 Types of components in and test their performance. In this process, reflective plates (mirrors) were used as optical path controllers, products from Thorlabs (WPQ05M-532) were used as retarders (3021, 3022), and PBS (polarization beam splitter) products from Thorlabs were also applied ( PBS251) as a polarization splitter. A Genesis MX SLM laser from Coherent Inc. (power 10 mW) was incident on the element as described above to test the element. The forward transmittance obtained in this way is about 76%, the reverse transmittance is about 36%, and the isolation ratio (IR) is about 3.2 dB.

Abstract

The present application relates to an optical isolation apparatus. Provided in the present application is an optical isolation apparatus having an excellent optical isolation rate which can be simplyformed at a low cost. The optical isolation apparatus can be applied to various purposes including, for example, optical communication or laser optics fields, security, and privacy protection fields,and to enhance the luminance of display or for concealment and cover purposes.

Description

technical field [0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2016-0132840 filed on October 13, 2016, the disclosure of which is incorporated herein by reference in its entirety. [0002] The present application relates to an optical isolation device. Background technique [0003] An optical isolation device is a device in which the transmittance of light in the forward direction is higher than that in the reverse direction, which is also called an optical diode. Optical isolators can be used to prevent unwanted reflected light in the fields of optical communication or laser optics, or they can also be applied to building or automotive glass for security or privacy protection, etc. Optical isolation devices can also be used in applications such as brightness enhancement in various displays or military products for concealment and concealment. [0004] As an optical isolator, there is a Faraday optical isolator using the Fa...
