AbstractOptical modulation method is one of the key factors in the optical link design for MRI RF coil interlinks. In this work, link performances of direct modulation by laser diode and external modulation by Mach Zehnder Interferometer are compared in the aspects of power gain, modulation bandwidth, noise figure and dynamic range. An external optical link can achieve better performance by the use of a low noise and high power laser. However, a direct optical link shows advantages in link structure, compact size and low cost. It is more feasible in engineering for large coil array interlinks.
