EOM technologies EOMs can be based on many operating principles and platforms. One can divide the EOMs in two categories – phase and amplitude modulation. In the following some prominent approaches in SiPh are presented. Operating principles for phase modulation are the plasma dispersion effect, pockels effect, interband transitions, and carrier accumulation/depletion+Franz-Keldysh effect. For the amplitude modulation some operating principles are the Franz-Keldysh effect, quantum confined Stark effect, and electrical gating.
