Abstract: A frequency-conversion method that uses a nonlinear optical process to transfer energy between a surface-plasmon (SP) wave that is guided along an electrically conducting strip and a light beam that is guided along an optical waveguide whose core is adjacent to the electrically conducting strip. A periodic structure spatially modulates the nonlinear susceptibility of the waveguide core with a spatial period that is related to a momentum mismatch in the nonlinear optical process. The spatial modulation provides quasi-phase matching for the SP wave and the light beam and enables efficient energy transfer between them.

Abstract: A hybrid strip-loaded 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 Γ and reduces inter-electrode separation d thereby lowering the modulator's half-wave drive voltage Vπ, reducing insertion loss and improving extinction. The strip-loaded modulator comprises an EO polymer layer that eliminates optical scattering caused by sidewall roughness due to etching. Light does not encounter rough edges as it transitions to and from the sol-gel and EO polymer waveguides. This reduces insertion loss.
