Abstract
The single sideband (SSB) modulator described by Carter and Haus1 has limitations over a broadband frequencies. To maximize the output of their device with CdTe in a square waveguide, the beat frequency of the laser and the sideband are phase matched with the microwaves. The dimension of the guide a is determined by satisfying the equation where β1,2 are the propagation constants of the sideband and the laser beams respectively in CdTe at 10.6 μm, ϵ =7.2, ϵμ =10.4. Equation(1) is satisfied for a =5.2 mm and fμ =16 GHz. When the microwave frequency deviates from this value , then the output is reduced according to the solution of the coupled-mode equations.1
