摘要： A plastic optical fiber communication system includes a light source that emits a first signal having a first wavelength in a visible light spectrum, the first signal being encoded with information at a high data-rate of 0.1 to 10 Gbit/s; a pump laser system that emits a pump laser light having a second wavelength, different from the first wavelength; a perovskite-doped optical fiber excited by the pump laser light to generate an amplified spontaneous emission spectrum that encompasses the first wavelength so as to receive and amplify the first signal for generating an amplified output signal having the first wavelength; and a photodetector optically coupled to the perovskite-doped optical fiber, and configured to receive the amplified output signal at the high data-rate of 0.1 to 10 Gbit/s. The amplified output signal is encoded with the information.

摘要： A high-speed, wavelength-converting receiver that includes a housing; a high-speed, wavelength-converting layer attached to the housing and configured to absorb a first light having a first wavelength range and emit a second light having a second wavelength range, which is different from the first wavelength range; and a high-speed photodetector attached to the housing and having an active face configured to absorb the second light having the second wavelength range and generate an electrical signal. The active face of the photodetector is fully placed within the housing.

摘要： A large-area, waveguide-based, high-speed ultraviolet and visible light photodetector system for optical wireless communication includes a substrate; plural, parallel, waveguides formed directly on the substrate and including a high quantum-yield wavelength-converting material of semiconductor nature; an optical coupling system optically connected to each one of the plural, parallel, waveguides; and a photodetector optically connected to the optical coupling system and configured to detect an outgoing light. The wavelength-converting material converts a first wavelength of an incoming light at high-speed, received by the plural, parallel, waveguides, into a second wavelength of the outgoing light. The first wavelength is different from the second wavelength, and the first and second wavelengths are between 200 and 800 nm.

摘要： A free node to be deployed underwater for omnidirectional energy and data harvesting includes a housing that forms a sealed chamber; a wavelength-changing layer attached to an outside of the housing and configured to receive a first optical signal having a first wavelength range and to emit a second optical signal having a second wavelength range, different from the first wavelength range, wherein the first optical signal includes encoded data; a flexible solar cell wrapped around the housing, the flexible solar cell being configured to receive the second optical signal and generate an electrical signal; an energy storage module located in the chamber and configured to store electrical energy associated with the electrical signal; and a decoder located in the chamber and configured to receive the electrical signal and decode the encoded data. The first wavelength range is ultraviolet light and the second wavelength range is visible or infrared light.
