TL;DR: This paper reports a technique that transforms a FBG into a Bragg cell or acousto-optic modulator operating in reflection mode.
Abstract: Summary form only given. Fiber Bragg gratings (FBGs) written with ultraviolet light are becoming of increasing importance in fiber systems because of their high performance, versatility, and excellent physical characteristics. In this paper, we report a technique that transforms a FBG into a Bragg cell or acousto-optic modulator operating in reflection mode.

TL;DR: In this paper, the first demonstration of a 40 MHz four-port all-fiber frequency shifter operating at a wavelength of 1.55 /spl mu/m was presented.
Abstract: We report the first demonstration of a 40 MHz four-port all-fiber frequency shifter operating at a wavelength of 1.55 /spl mu/m. The device has a high-conversion efficiency and low-drive power consumption, and is made from standard telecommunications fiber.

01 Jan 1996TL;DR: In this article, the coupler was made more uniform and a double-pass arrangement was proposed to further narrow the bandwidth, reduce the sidelobes, and double the frequency shift of the null coupler.
Abstract: Tunable acousto-optic spectral filters based on null couplers have been improved by making the coupler more uniform A new double-pass arrangement further narrows the bandwidth, reduces the sidelobes to -20 dB and doubles the frequency shift
