    摘要： Provided is a mode converter for use in optical communication. The mode converter includes a first waveguide, a second waveguide optically coupled into the first waveguide, and omnidirectional reflectors that are disposed on either side of the first waveguide and have forward reflectivity with respect to a mode propagating in the first waveguide. The mode converter provides minimum loss coupling between either optical fiber or low index difference waveguide and a high index contrast waveguide. Furthermore, the mode converter achieves high, bi-directional optical coupling over a wide wavelength range with a simple manufacturing process.

    摘要： An illumination system for a flat panel display device includes: a light guide plate made of an optically isotropic material; a light source disposed at a side of the light guide plate; an upper layer disposed on a top surface of the light guide plate and made of an optically anisotropic material; and a polarization selection emitting structure which is disposed at an interface of the light guide plate and the upper layer. The upper layer has two different refractive indices and one of the two refractive indices is the same as a refractive index of the light guide plate. In the polarization selection emitting structure differently polarized light is differently refracted, reflected, diffracted, or scattered based on polarization direction.
