OPTICAL MODULATION ELEMENT, OPTICAL SHUTTER, AND OPTICAL MODULATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18456531 titled 'OPTICAL MODULATION ELEMENT, OPTICAL SHUTTER, AND OPTICAL MODULATION METHOD

Simplified Explanation

The patent application describes an optical modulation element that can dynamically modulate reflected or transmitted light by changing the voltage applied to a light absorbing layer. The element includes a substrate, an electrode layer, a dielectric layer, and a light absorbing layer containing inorganic nanoparticles that exhibit localized surface plasmon resonance when exposed to light.

  • The optical modulation element can dynamically modulate reflected or transmitted light by changing the voltage applied to the light absorbing layer.
  • The element includes a substrate, an electrode layer, a dielectric layer, and a light absorbing layer containing inorganic nanoparticles.
  • The inorganic nanoparticles exhibit localized surface plasmon resonance when exposed to light, allowing for modulation of light.

Potential Applications

  • Optical shutters for controlling the amount of light passing through a window or display.
  • Smart windows that can switch between transparent and opaque states.
  • Optical switches for telecommunications and data communication systems.
  • Light modulators for optical signal processing and imaging applications.

Problems Solved

  • Traditional optical modulation techniques may be limited in their speed, efficiency, or flexibility.
  • The use of inorganic nanoparticles with localized surface plasmon resonance allows for faster and more efficient modulation of light.
  • The ability to dynamically change the voltage applied to the light absorbing layer provides greater control over the modulation process.

Benefits

  • Faster and more efficient modulation of light.
  • Greater control and flexibility in adjusting the modulation of light.
  • Potential for improved performance and functionality in various optical applications.
