Abstract
We propose and theoretically analyze a novel transmitter
emitting <i>m</i> wavelength-division multiplexed and independently
modulated optical signals. The transmitter is based on an extended
cavity formed by <i>m</i> wavelength-agnostic reflective
semiconductor optical amplifiers (one for each wavelength) on one
end and a single modulation-averaging reflector on the other end of
the cavity. We show that optimally designed modulation-averaging
reflectors can efficiently change the intensity probability density
function from bound bit-stream modulation to a normal distribution
and thereby improve signal-to-noise ratio of all emitted optical
signals. This improvement may potentially allow the realization of
cost-efficient wavelength division multiplexing passive optical
networks (WDM-PON).
