Phosphor-Loaded Waveguides for Improved Security

Waveguides are a critical component in various optical systems, carrying light from one point to another. However, maintaining a high level of light transmission can be challenging in waveguides, especially if the structure is insufficient to maximize light introduction. Additionally, waveguides that are transparent to probing can invite security issues. Current waveguides often suffer from limitations due to the undermining of light introduction. The lack of diverse light sources and insufficient light within the waveguide often lead to underperformance in light transmission and, in turn, overall system efficiency. Moreover, being prone to probing can compromise the optical system's confidentiality and data integrity.

Technology Description

The presented waveguide is an innovative optical solution tailored to boost light introduction. It employs a luminescent material that can be placed within or around its perimeter. This waveguide can comprise several planar layers, each having diverse refractive indexes, and the luminescent material can be arranged along the edge of these layers. Once the light within the waveguide encounters the luminescent material, it emits light thereby supplementing the waveguide's light. This waveguide holds distinct advantages. The integration of luminescent material not only enhances the amount of light introduced into the waveguide, but it also adds more light sources inside. This additional light introduces a unique challenge to probe introduction, making it a task to probe the waveguide without obstructing some portion of the destined light. The luminescent material chosen can be a phosphor.
