Model for a Torsional-Mode Ultrasonic Transducer for an Acousto-Optic In-Fiber Isolator
Figure 11
Axial wavelength (left of cutoff resonances) and attenuation length (right of resonances) is shown as a function of temperature for several fiber diameters. The frequency is chosen to produce an axial wavelength of 3 mm at 20 C for a m-diameter fiber.
