摘要： Provided is an optical device having an optical waveguide including an organic Bragg grating sheet. The optical device includes a cladding layer, and an optical waveguide. The cladding layer is formed on a substrate, and the optical waveguide is formed within the cladding layer. The optical waveguide includes a core layer and an organic Bragg grating sheet located within the core layer. The organic Bragg grating sheet has a refractive index higher than that of the core layer to reflect or transmit light having a predetermined wavelength. Accordingly, light propagates through the optical waveguide with high reflectance and low loss. Besides, a high performance tunable wavelength filter or tunable dispersion compensator may be constructed by forming a thermal electrode on the optical waveguide, forming a tapered optical waveguide, or forming a chirped organic Bragg grating sheet in the middle of the core layer of the optical waveguide.

摘要： A polyamic ester (PAE) film, which shows an electro-optic (EO) and nonlinear optical (NLO) properties without a poling process, is prepared. The chromophore in the film seems to be slightly oriented normally to the film surface (transverse magnetic field (TM) direction even though the polymer solution is spin-coated. This is due to the nano-configuration structure of PAE controlled by introducing a designed chemical structure into the monomeric repeating unit of PAE. Manufacturing the relating devices can be simplified by using the self-poled polymer film as a polymer waveguide. Additionally, the EO property of the film is thermodynamically stable.

摘要： Provided is an optical waveguide device including: a core having a stacked structure of at least three layers in which first thin films having a finite width and thickness and formed of a material having a relatively high electric conductivity and a second thin film having the same width as the first thin films and formed of a material having a lower conductivity than the material forming the first thin films are stacked in sequence, the first thin films being disposed in a first layer and an uppermost layer and adjacent to each other for interaction of surface plasmons; and a clad disposed around the core and formed of a material having a lower conductivity than the material forming the first thin films and a higher refractive index than the material forming the second thin film. The thin metal films of at least two layers having a high electric conductivity in the optical waveguide device can generate a combined surface plasmon mode and propagate the generated surface plasmon mode in the length direction of the thin metal films. Thus, a propagated signal suffers from a smaller propagation loss than a surface plasmon mode supported by a single thin film.
