Abstract:
Parallel spectral multiplexing of LED radiation by a diffraction grating accompanied by spectral filtering was proposed and implemented. This made it possible to reduce the spectral intervals between the channels to 20 nm and the crosstalk level to less than – 20 dB, which had been achieved earlier only for semiconductor laser radiation. Spectral multiplexing of radiation of five fiber waveguides was achieved in a transparency "window" near the wavelength of 0.8 μ. A single fiber with a quartz glass core and a polymer cladding transmitted five analog television signals over a distance of 4 km.
