摘要
Dispersion control is a critical functionality required in systems involving ultra-short (similar to 100 fs) pulses, and we demonstrate the use of chirped long-period fiber gratings for this purpose. The operation principles of this device share many attributes with the more established fiber Bragg grating technology for dispersion compensation, but with the added benefit of record low loss (0.2 dB) and the potential of being free from group-delay ripple distortions. The bandwidth of the transmissive grating device we demonstrate exceeds 12 nm, and it provides +52 fs/ nm of dispersion in the 1 ae m wavelength range. This corresponds to the capability of compensating the dispersion of similar to 100 fs pulses in approximately meter-long single mode fibers.
