Hybrid Electro-Optic Polymer/Sol-Gel Modulator

摘要

A hybrid EO polymer/sol-gel modulator in which the sol-gel core waveguide does not lie below the active EO polymer waveguide increases the higher electric field/optical field overlap factor Gamma and reduces inter-electrode separation d thereby lowering the modulator's half-wave drive voltage Vpi, reducing insertion loss and improving extinction.
