HIGH-RESPONSE ELECTRO-OPTIC MODULATOR BASED ON AN INTRINSICALLY ACENTRIC, LAYER-BY-LAYER SELF-ASSEMBLED MOLECULAR SUPERLATTICE

摘要

A new electro-optic (EO) phase modulator (100) constructed from a combination of a low loss passive polymer waveguide (80) and a self-assembled chromophore superlattice (SAS) (50) with an intrinsically polar microstructure. In constrast to typical polymer-based modulators, the present invention utilizes a siloxane SA (12) methodology that enables the acentric alignment of constituent chromophores during film growth without the need for post-deposition electric field poling. The guiding layer is constructed of the SAS (50) and the glassy polymer CycloteneTM (90). The use of SiO2, CytopTM and CycloteneTM glassy polymers (90), results in a straightforward device fabrication process that is compatible with the thermally and photochemically robust SAS. Thus, nanoscale control of the film architecture results in greatly simplified macroscopic device fabrication. The present invention provides a SAS-based electro-optic modulator (100) demonstrating excellent electro-optic response properties and p phase shift.
