    摘要: An EO polymer modulator including a substrate with a cladding layer formed on a surface and a passive waveguide core, having a cross-sectional area, formed in the cladding layer and including an elongated tapered active section. An elongated trench in the cladding layer, the elongated tapered active section of the waveguide core positioned in the elongated trench, electrodes positioned on a surface of the cladding layer on opposite sides of the elongated trench, and an elongated strip of EO polymer overlying the elongated tapered active section of the waveguide core. The elongated strip of EO polymer positioned between and parallel with the electrodes and coplanar with the electrodes.

    摘要: A monolithic PIC including a monolithic laser formed in/on a platform and a polymer modulator monolithically built onto the platform and optically coupled to the laser. The modulator includes a first cladding layer, a passive core region with a surface abutting a surface of the first cladding layer, the core region extending to define an input and an output for the modulator. A shaped electro-optic polymer active component has a surface abutting a surface of a central portion of the core region. The active component is polled to align dipoles and promote modulation of light and has a length that extends only within a modulation area defined by modulation electrodes. A second cladding layer encloses the active component and is designed to produce adiabatic transition of light waves traveling in the core region into the active component to travel the length thereof and return to the core region.

    摘要: A polymer waveguide/modulator including a lower cladding layer, a polymer core, an upper cladding layer, a first protection/barrier layer sandwiched between the lower cladding layer and the core, and a second protection/barrier layer sandwiched between the core and the upper cladding layer. The protection/barrier layers designed to protect the cladding layers and the core from solvents and gases and to prevent current leakage between the cladding layers and the core. The first protection/barrier layer is optically transparent and designed with a refractive index less than, greater than, or the same as the refractive index of the core and approximately equal to the refractive index of the lower cladding layer. The second protection/barrier layer is optically transparent and designed with a refractive index less than, greater than, or the same as the refractive index of the core and approximately equal to the refractive index of the upper cladding layer.
