Abstract:
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.
