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.
我们展示了一种可变光延迟元件，它利用周期性极化铌酸锂波导中的可调谐波长转换、色散补偿光纤和通道内色散补偿。使用80Gb/s归零差分正交相移键控、40Gb/s归零差分相移键控和40Gb/s归零开关键控调制格式，展示了高达105纳秒的延迟。在各种延迟设置下，每种波形的误码率均<10(-9)。
