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 105ns is demonstrated using 80Gbs return-to-zero differential-quadrature phase-shift keying, 40Gbs return-to-zero differential phase-shift keying, and 40Gbs return-to-zero on–off keying modulation formats. Bit-error rates <109 are demonstrated for each waveform at various delay settings.

Conceptual diagram of tunable delay using wavelength conversion plus dispersion. λ o is the input signal; λ p 1 , λ d 1 , λ p 2 , and λ d 2 are the pump and dummy wavelengths for the first and second PPLN waveguide, respectively; and λ c is the converted wavelength. OBPF, optical bandpass filter.

The amount of delay depends on the wavelength conversion range and the total dispersion of the DCF.

Experimental setup. Transmitter is capable of generating 80 Gb s RZ-DQPSK, 40 Gb s RZ-DPSK, and 40 Gb s RZ-OOK modulation formats. Phase demodulation at the receiver for DPSK/DQPSK is performed with a single interferometer tuned to the appropriate location (I and Q measured separately).
