We demonstrate a method for dispersion slope compensation of a conversion/dispersion-based optical delay to enable operation based on a spatial light modulator and fiber Bragg gratings. A continuous delay of up to for 100, 80, and differential quadrature phase-shift-keyed (DQSPK) and 50, 40, and differential phase-shift-keyed (DPSK) waveforms is shown. A time-delay bit-rate product of ~360,000 for DQPSK with wavelength-maintaining operation is achieved.
