Abstract

Diffraction of light on Bragg gratings has attracted much attention for fundamental reasons and for applications to optical signal processing.^1,2 However, the Bragg diffraction properties of thick gratings are often insufficient for practical applications. As shown recently³ this limitation can be overcome by placing a sinusoidal grating inside a Fabry- Perot cavity. Here, we show that the diffracted intensities can be even much higher than the incident ones if the intracavity Bragg medium is made amplifying.
