Piezoelectric optical fiber phase modulator is to assemble piezoelectric actuator into a flexible hinge structure. The structure can output the displacement and output of the piezoelectric actuator, and can wind the optical fiber on it. The displacement generated by the piezoelectric ceramics is output in the radial direction to stretch the fiber.
N01 series optical fiber phase modulator is piezoelectric motion mechanism specially designed for fiber stretching applications. Its principle is to cause the hinge structure to expand to the outside through the actuation of three piezoelectric ceramic stacks placed equally at 120 degrees. , So that the outer diameter expands, thereby stretching the optical fiber wound in the outer diameter groove.
According to different applications, CoreMorrow N01 series optical fiber phase modulators can be divided into large blocking force type and large displacement type. Users can choose corresponding types of products according to different applications.
