Abstract: In an optical fiber communication system a pulse reshaper can transform a distorted input light pulse into a reshaped output light pulse. The disclosed pulse reshaper is an all-optical pulse reshaper that comprises an optical waveguide having an effective length, the waveguide connecting the input and the output and comprising optical non-linear material, with a periodic variation of an effective refractive index of the optical waveguide. The optically non-liner material and the periodic variation are selected such that the reshaped output light pulse is a substantially transform-limited output light pulse.

Abstract: A tunable chromatic dispersion compensator for optical communication syste ms is disclosed. An optical grating, such as a fiber Bragg grating, non-chirped , linearly chirped or non-linearly chirped, is coated on its outer surface with a coati ng have a variable diameter and strained is applied to the fiber. The fiber may be latchably strained so that the grating characteristics may be changed or tuned while avoiding u se of a continuous power supply. Various optical networking applications using such dispersion compensating devices are also disclosed.

Abstract: A method for making a chirped grating device capable of a broad bandwid th for optical communication systems is disclosed. An intrinsically-chirped optical grating is externally strained to alter the range of chirping. The external strain may be induced by a gradient-generating body bonded onto the length of the fiber grating that may be latchably strained so that the grating characteristics may be changed or tuned while avoiding use of a continuous power supply. Various optical networking applications using such dispersion compensating devices are also disclosed.

Abstract: In accordance with the invention, an optical pulse compressor comprises a pulse source (10), a section of nonlinear optical waveguide (11) including a periodic structure such as Bragg grating (12), for providing positive dispersion and a section of linear optical waveguide (13) including a negative dispersion component (14). The nonlinear waveguide should have a second order index N2 at least ten times the second order index N2' of the linear waveguide. The nonlinear waveguide is preferably chalcogenide fiber, with a Bragg grating photoinduced into the core. Because the grating is 4-5 orders of magnitude more dispersive than standard optical fiber, the length of the nonlinear waveguide section can be scaled down to a few centimeters with accompanying reduction of deleterious processes. Modeling suggests that compression factors of 5 with an initial 60 ps pulse are achievable with grating lengths of about 20 cm.

Abstract: In accordance with the invention, a reconfigurable optical fiber grating comprises an optical fiber grating with a temperature sensitive material surrounding the cladding region or incorporated into the cladding region. One or more heating elements are arranged to produce a a temperature gradient along the length of the grating and thereby chirp the grating. In a preferred embodiment, a long period fiber grating is surrounded by a material in which dn/dT is 10 times as large as that of glass and in which n is close to but lower than that of the glass. A temperature gradient along the length of the grating results in a broadening of the resonance.
