Abstract
We propose and demonstrate a new all-fiber-optic nonreciprocal device without using magnetic field and Faraday effect. The device is based on a nonreciprocal phase shift produced by a set of acousto-optic frequency shifters, that is used in an interferometer to form a nonreciprocal intensity transmitter. The device is a Mach-Zehnder interferometer with two reciprocal frequency shifters in one of the arms, that shift the optical frequency up and down
