Paper Abstract

The concept of two magnetically tunable electro-optic (EO) modulators is described. A single-sideband in which the E-O crystal is surrounded by a hollow square tube of ferrite is axially magnetized in a square waveguide. The other is a double sideband device in a rectangular waveguide with the E-O crystal sandwiched between two ferrite slabs oppositely magnetized transverse to the waveguide. Each is tuned by a variable magnetic field in order to match the phase velocities of the varying microwave frequency and the optical velocity of the laser beam. Perturbation theory yields tuning curves of frequency versus magnetic field over a relatively broadband.
