Optical Transmitter - A simplified explanation of the abstract
This abstract first appeared for US patent application 18258396 titled 'Optical Transmitter
The abstract describes an optical transmitter that multiplexes wavelength channels using multiple light sources, collimator lenses, an optical multiplexer, and beam splitters.
- The optical transmitter includes a first light source and one or more second light sources with different wavelengths.
- Collimator lenses are coupled to the outputs of the light sources to focus the light beams.
- An optical multiplexer directs the output light beams from the light sources to different paths, reflecting and filtering them before multiplexing them.
- Beam splitters are inserted between the collimator lenses and the optical multiplexer to further manipulate the light beams.
Potential Applications: - Optical communication systems - Fiber optic networks - Data transmission technologies
Problems Solved: - Efficient multiplexing of wavelength channels - Improved data transmission speeds - Enhanced optical communication capabilities
Benefits: - Increased data transmission capacity - Enhanced network performance - Improved signal quality
Commercial Applications: Title: "Advanced Optical Transmitter for High-Speed Data Transmission" This technology can be used in telecommunications, data centers, and internet infrastructure to improve data transmission efficiency and speed.
Questions about the technology: 1. How does the optical multiplexer manage the output light beams from different light sources? 2. What are the advantages of using multiple light sources with different wavelengths in the transmitter?
Original Abstract Submitted
An optical transmitter that multiplexes wavelength channels includes: a first light source; one or more second light source each having a different wavelength; collimator lenses coupled to respective outputs of the first and second light sources; an optical multiplexer that causes an output light beam from the first light source to be transmitted from a first end surface to a second end surface, causes the output light beam from the first light source to be reflected by a reflecting mirror, causes an output light beam from the second light source to pass through a wavelength filter, causes the output light beam from the second light source to be reflected by the reflecting mirror, and causes output light beams of the respective wavelength channels, to sequentially multiplex the output light beams of the respective wavelength channels; and beam splitters respectively inserted between the collimator lenses and the first end surface.
