Abstract

A step-chirped step-apodized transmission grating is proposed to maximize compression ratio, minimize compensating length, and improve recompressed pulse shape of a 40-ps (FWHM) Gaussian pulse, broadened and chirped upon transmission in a 100 km length of optical fiber. This is accomplished by tuning a single transmission side lobe to lie within or coincide with the pulse bandwidth at the upper edge of the photonic band gap of each grating section. Analysis is via the theory of uniform cascaded gratings achieving a compression ratio of 5.625 in a four-section grating 3.422 cm long.
