Interferometric power amplifiers
Optics Letters, 1989A general method of producing multielement amplifiers having a single output beam is described. The basic building blocks for these are either Michelson interferometers or Mach-Zehnder interferometers modified by the inclusion of gain in at least one arm of the interferometer.

Summary form only given. Computer Aided Engineering tools can be particularly useful for simulating and designing power amplifiers. This presentation outlines some of the simulations that can be carried out and includes a number simulation results. Power amplifier design often can be enhanced by nonlinear simulation, provided that an accurate model is ...
