Characteristics of chirped fiber gratings for dispersion compensation

Summary form only given. Chirped fiber Bragg gratings have recently received considerable attention due to their immense potential for use as dispersion equalizers in long-haul fiber telecom links. Some of their properties have been studied theoretically and demonstrated in a number of system trials. We have implemented a variable-chirp grating using the temperature gradient technique and systematically measured its reflection and dispersion characteristics for a wide range of applied chirp.
