Large bandwidth optical communication systems utilizing an incoherent optical source |
摘要 |
The dispersion of optical signals derived from a spontaneous emitter when coupled into an optical fiber waveguide is substantially reduced by optically coupling a narrow band pass interference filter between the emitter and waveguide. Only a narrow portion of the broad spectral width emission of the emitter is thereby coupled into the waveguide to provide emitter modulation rates limited only by the rise-time of the emitter. In the preferred embodiment, the coupled spectral portion corresponds to the wavelengths of peak emission. Additionally, the filter is a thin film filter deposited onto either the light-exiting face of the emitter or onto the light-receiving end of the fiber waveguide.
