Abstract
ABSTRACT A Fabry-Perot etalon, consisting of two phase shifted reflecting volume Bragg gr atings, is presented. These gratings are obtained as a moire pattern resulting from sequential recording of interference patterns with different periods in photo-thermo-refractive glass and called moire volume Bragg gratings (MVBGs). A detailed investigation of the fundamental operating principles and meas urement techniques for phase shifted gratings is shown. Experimental results demonstrating a MVBG with a 15 pm bandwidth and 90% transmission at resonance are presented. The use of the MVBG for longitudinal mode selection in a laser resonator is shown. Keywords: Spectral filter, single frequency, mode selector, holography 1. INTRODUCTION Narrow bandwidth sources find many applications in the fields of spectroscopy, metrology, WDM communication systems and optical sensor networks. Thin film filters and Fabry-Perot etalons are commonly used to create narrow bandwidth filters with large apertures
