ABSTRACT:
The present invention relates to a potentially inexpensive light for multi-channel wavelength-division-multiplexed (WDM) applications. The high-power amplified spontaneous emission (ASE) from a fiber amplifier, which is already in the optical fiber, is efficiently divided into many channels using a WDM demultiplexer. This "spectrum-sliced" ASE is used as light sources for WDM systems rather than several wavelength-selected DFB lasers.
