OPTICAL WAVEGUIDE COUPLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18603136 titled 'OPTICAL WAVEGUIDE COUPLER
Simplified Explanation:
This patent application describes a structure with two waveguides that guide light, where the tips of the waveguides are optically coupled to each other.
- The structure includes a first waveguide with a strip portion and a tapered tip portion, and a second waveguide with a strip portion and a tapered tip portion.
- The first tapered tip portion of the first waveguide is optically coupled to the second tapered tip portion of the second waveguide.
- The effective refractive index of the first waveguide is substantially equal to that of the second waveguide in the region where light is coupled between the tapered tip portions.
Key Features and Innovation:
- Optically coupled waveguides for guiding light.
- Equal effective refractive indices in the coupling region.
Potential Applications:
- Optical communication systems.
- Photonic integrated circuits.
- Sensing applications.
Problems Solved:
- Efficient light guiding.
- Precise optical coupling.
Benefits:
- Improved light transmission.
- Enhanced optical communication.
Commercial Applications:
Optical communication technology for data centers and telecommunications industry.
Questions about Optical Coupled Waveguides:
1. How do optically coupled waveguides improve light transmission efficiency? 2. What are the potential applications of structures with equal effective refractive indices in the coupling region?
Original Abstract Submitted
A structure includes a first waveguide and a second waveguide. The first waveguide includes a first strip portion and a first tapered tip portion connected to the first strip portion. The second waveguide includes a second strip portion and a second tapered tip portion connected to the second strip portion, wherein the first tapered tip portion of the first waveguide is optically coupled to the second tapered tip portion of the second waveguide, and the first waveguide and the second waveguide are configured to guide a light. In a region where the light is coupled between the first tapered tip portion and the second tapered tip portion, an effective refractive index of the first waveguide with respect to the light is substantially equal to an effective refractive index of the second waveguide with respect to the light.
