Abstract

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.¹ Some of their properties have been studied theoretically and demonstrated in a number of system trials.² We have implemented a variable-chirp grating using the temperature gradient technique³ and systematically measured its reflection and dispersion characteristics⁴ for a wide range of applied chirp. The results, which are in very good agreement with theoretical predictions, clarify those properties and will be discussed in this paper.
