Abstract

A significant improvement in the performance of position tuned volume reflection gratings in Dichromated Gelatin ( DCG) for fibre based applications in the 1200-l600nm range is reported. Spectral widths of less than 5nm at the Full Width at Half Maximum, have been obtained over the whole tuning range, with high peak efficiences for DCG films of 410 microns in thickness. This performance represents an effective utilisation of the film volume of 60 -70%.
