For high bit-rate dense wavelength-division multiplexed (DWDM) applications fiber grating dispersion for the transmitted adjacent channels is shown to be detrimental and ultimately leads to a penalty. We consider design criteria for fiber grating filters in DWDM systems using both Gaussian pulses and super-Gaussian pulses that approximate square pulses that(More)
We demonstrate a tunable dispersion slope compensator using a linearly chirped fiber Bragg grating and a thin-film heater that provides a variable quadratic temperature gradient along the grating. We achieved 2-10-ps/nm/sup 2/ compensation over 3 nm suitable for 160-Gb/s return-to-zero signals.
We propose a simple physical model that predicts spectral resonances of a class of microstructured optical waveguides consisting of high-index inclusions surrounding a low-index core. These resonances are largely determined by the geometry of individual high-index inclusions.
