Abstract

We demonstrate a variable, optical-delay element using tunable wavelength conversion in a periodically poled lithium niobate waveguide, dispersion-compensating fiber and intrachannel dispersion compensation. A delay of up to 105 ns is demonstrated using 80 Gb s return-to-zero differential-quadrature phase-shift keying, 40 Gb s return-to-zero differential phase-shift keying, and 40 Gb s return-to-zero on–off keying modulation formats. Bit-error rates < 10 9 are demonstrated for each waveform at various delay settings.
