Abstract

In-fiber chirped Moiré resonators are excellent filters in terms of fiber compatibility, and can potentially provide wide stopbands, narrow passbands and high rejection levels. This paper describes the realization of chirped Moire in- fiber filters written using phase mask techniques. The filters described here were fabricated both from the dual exposure of a uniform-pitch phase mask followed by a third refractive index profiling scan and from the dual exposure of chirped phase masks. These techniques produce filters that replicate the broad bandwidths associated with holographic techniques and have the advantage of the good reproducibility associated with the use of phase masks.
