Electronic Devices with High Frequency Symbol Generation - A simplified explanation of the abstract

This abstract first appeared for US patent application 17895860 titled 'Electronic Devices with High Frequency Symbol Generation

Simplified Explanation

The abstract describes an electronic device that utilizes optical demultiplexing, optical combiners, modulators, and a symbol generator to generate and combine optical OFDM symbols for transmission.

• Optical demultiplexer separates optical signals into different channels
• Modulators mix electrical OFDM symbols with optical carriers to generate optical OFDM symbols
• Optical combiners combine optical OFDM symbols to create an aggregate optical OFDM symbol
• Aggregate optical OFDM symbol is combined with an optical local oscillator signal
• Photodiode converts the combined signal into a radio-frequency signal above 100 GHz

Potential Applications: - High-speed wireless communication systems - Optical communication networks - Radio astronomy for high-frequency signal detection

Problems Solved: - Efficient generation and transmission of high-frequency signals - Increased bandwidth for data transmission - Integration of optical and radio-frequency signals

Benefits: - High-speed data transmission capabilities - Enhanced signal quality and reliability - Improved efficiency in communication systems

Original Abstract Submitted

An electronic device may include an optical demultiplexer, optical combiners, optical paths between the demultiplexer and the combiners, modulators on the optical paths, and a symbol generator that generates a set of electrical OFDM symbols. The modulators may generate a set of optical OFDM symbols by mixing optical carriers with the electrical OFDM symbols. The combiners may generate an aggregate optical OFDM symbol from the optical OFDM symbols and may combine the aggregate optical OFDM symbol with an optical local oscillator signal. The aggregate optical OFDM symbol may exhibit a large bandwidth. The combiners may illuminate a photodiode, which produces current on an antenna resonating element that radiates a radio-frequency signal at frequencies greater than 100 GHz.
