High-performance electro-optic polymers and their applications in high-speed electro-optic switches and modulators

摘要

Abstract: Recent progress in the development and application ofhighly active, highly thermally stable, and low opticalloss electro-optic polymers is presented. Nonlinearoptical chromophores with large molecularnonlinearities and high thermal and chemicalstabilities are covalently attached to optical gradepolyimides to form side-chain polymers withelectro-optic coefficients as high as 45 pm/V andlifetime over 10$+6$/ hours at 100 degrees Celsius.Cladding polymers with matching optical, mechanical,and electrical properties have been formulated andprocessed. Using a novel trench- and-fill process,integrated high speed electro-optic switches andmodulators have been fabricated and tested. !17
