Narrow-bandwidth holographic reflection filters with photopolymer films

Narrow-bandwidth holographic reflection filters are demonstrated that use volume gratings in 100-mum-thick photopolymer films. A full width at half-maximum of 0.09 nm can be achieved with similar to 35% peak reflectance near the 900-nm region. Detailed fabrication procedures and filter performances are described.
