Optical Apparatus, Modules and Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 18293432 titled 'Optical Apparatus, Modules and Devices
The apparatus described in the patent application consists of two light waveguides, each with diffraction gratings and expanders to manipulate input beams of light from respective light engines.
- The first light waveguide includes a diffraction grating to couple light from a first light engine, an expander to expand the light beams, and a diffraction grating to out-couple the expanded beams.
- The second light waveguide follows a similar structure, with components to couple, expand, and out-couple light from a second light engine.
Potential Applications: - Optical communication systems - Laser systems - Fiber optic networks
Problems Solved: - Efficient manipulation of light beams - Precise control of light propagation
Benefits: - Enhanced performance of optical systems - Improved signal transmission in fiber optics
Commercial Applications: Title: Advanced Optical Communication Systems This technology can be utilized in telecommunications, data centers, and scientific research facilities to enhance the efficiency and reliability of light-based systems.
Questions about the technology: 1. How does the diffraction grating in-couple and out-couple light beams in the waveguides? 2. What are the advantages of using expanders in manipulating light beams in this apparatus?
Original Abstract Submitted
An apparatus includes: a first light waveguide including at least: a first in-coupling diffraction grating to in-couple first input beams of light into the first light waveguide from a first light engine, a first expander to expand the first input beams of light from the first light engine to form first expanded beams of light, and a first out-coupling diffraction grating to out-couple the first expanded beams of light from the first light waveguide; a second light waveguide including at least: a second in-coupling diffraction grating to in-couple second input beams of light into the second light waveguide from a second light engine, a second expander to expand the second input beams of light from the second light engine to form second expanded beams of light, and a second out-coupling diffraction grating to out-couple the second expanded beams of light.
