Abstract
We demonstrate a broad-band time-division demultiplexer with inherent gain based on selective amplification in a fiber optical parametric amplifier Th e parametric amplifier is pumped by a CW light source being sinusoidally in tensity modulated by an optical Mach-Zehnder modulator. A switching window between 10% and 18% of the modulation period is measured over a 39 nm wavel ength range with a demultiplexed fiber gain of up to 40 dB. Four-wave mixin g based demultiplexing without wavelength conversion was achieved due: to t he high parametric gain. Bit-error-rate measurements show error-free demult iplexing at 40 to 10 Gb/s.
