Problems solved by technology

At present, mature optoelectronic oscillators generally require a long optical fiber as a delay energy storage device to improve the quality of the generated signal, but the large size of the long optical fiber limits the use of optoelectronic oscillators

However, the quality of the generated microwave signal is also limited due to the difficulty in achieving a large on-chip delay for the optoelectronic oscillator based on the integrated device on the chip.
