Higher-order dispersion compensation to enable a 3.6 (mu)s wavelength-maintaining delay of a 100 Gb/s DQPSK signal

摘要

We demonstrate a method for dispersion slope compensation of a conversion/dispersion-based optical delay to enable 100 Gb/s operation based on a spatial light modulator and fiber Bragg gratings. A continuous delay of up to 3.6 (mu)s for 100, 80, and 20 Gb/s differential quadrature phase-shift-keyed (DQSPK) and 50, 40, and 10 Gb/s differential phase-shift-keyed (DPSK) waveforms is shown. A time-delay bit-rate product of approx360,000 for 100 Gb/s DQPSK with wavelength-maintaining operation is achieved.
