TERAHERTZ WAVE-VISIBLE LIGHT CONVERSION DEVICE AND IMAGE SENSING DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17990475 titled 'TERAHERTZ WAVE-VISIBLE LIGHT CONVERSION DEVICE AND IMAGE SENSING DEVICE INCLUDING THE SAME

Simplified Explanation

The abstract describes a light conversion device that includes a substrate, metal patterns, a metal layer, a first slit, and a light-emitting layer. Here are the key points:

  • The device has a substrate, which serves as a base.
  • There are multiple metal patterns on the substrate, separated from each other.
  • A metal layer surrounds each of the metal patterns.
  • A first slit is positioned between the metal layer and each metal pattern, surrounding them.
  • The first slit and the metal pattern it surrounds are concentric.
  • The first slit is filled with a light-emitting layer.
  • When an invisible light wave is incident on the first slit, a first electric field enhancement occurs.

Potential applications of this technology:

  • Light conversion devices can be used in various fields such as display technologies, lighting systems, and optical communication.
  • The ability to enhance the electric field of invisible light waves can have applications in sensors, detectors, and imaging systems.

Problems solved by this technology:

  • The device provides a means to convert invisible light waves into visible light, enabling their detection and utilization.
  • The concentric design of the first slit and metal pattern enhances the electric field, improving the efficiency of light conversion.

Benefits of this technology:

  • The device offers a simplified and efficient method for converting invisible light into visible light.
  • The enhanced electric field allows for improved sensitivity and detection of invisible light waves.
  • The device can be integrated into existing systems and technologies, expanding their capabilities.


Original Abstract Submitted

A light conversion device includes a substrate; a plurality of metal patterns provided on the substrate and separated from each other; a metal layer provided on the substrate and surrounding each of the plurality of metal patterns; a first slit positioned between the metal layer and each of the plurality of metal patterns and surrounding each of the plurality of metal patterns; and a light-emitting layer filling the first slit. The first slit and the metal pattern surrounded by the first slit are concentric. The metal layer and the plurality of metal patterns are aligned so that a first electric field enhancement occurs when a wave belonging to an invisible light band is incident to the first slit.
