    摘要： The present application specifically relates to an electro-optic modulator, comprising: a substrate; a first dielectric layer, located on the substrate; an opening being formed in the first dielectric layer, and the opening exposing a portion of the substrate; a waveguide, located on the substrate and located at the bottom of the opening or below the opening; a first electrode, located in the first dielectric layer, located on one side of the waveguide, and spaced apart from the waveguide; a second electrode, located in the first dielectric layer, located on the side of the waveguide distant from the first electrode, and spaced apart from the waveguide; and an organic electro-optic material layer, at least located in the opening and at least covering the waveguide. In the electro-optic modulator of the embodiments, a common waveguide different from a slit waveguide is used, and the manufacturing process requirements are low; the organic electro-optic material layer is covered on the waveguide, so that a light field can be leaked into the organic electro-optic material to the maximum extent, thereby effectively reducing optical loss and having high electro-optic modulation efficiency.

    摘要： Observable changes in electrical and optical characteristics of individual molecules adsorbed on a conductor or semi-conductor caused by electrical and/or optical excitation or de-excitation of electrons within such molecules can be used as signals which in turn can be used to carry information and such observable information carrying changes or signals can be switched, amplified, and modulated by varying optical as well as electrical inputs to such molecules. Molecular structural design alters functional behavior of the molecular/quantum devices. In an example, monomeric metallated phthalocyanine behaves as a fast (

    摘要： An optical device (30) which utilizes a photothermal optical effect to achieve switching or attenuation includes a waveguide defined by a waveguide core (36) and a surrounding cladding (34), wherein the polymer waveguide core (36) includes a region (38) consisting of a photothermally responsive material having an absorption coefficient at a switch wavelength or attenuation wavelength that is higher than an absorption coefficient at a signal wavelength. Switching devices include an optical splitter circuit having a branch (36B) that includes the photothermally responsive material, and either a multiplexer for introducing light at the switch wavelength into the optical circuit or a light source (40) focused at the photothermally responsive material. Attenuating devices include a Mach-Zehnder type interferometer having a branch that includes the photothermally responsive material and either a multiplexer for introducing light at the attenuation wavelength into the optical circuit or a light source focused at the photothermally responsive material.

    摘要： A Mach-Zender interferometer employing a section of polymer cladding in one branch. The polymer cladding has an index of refraction that varies with temperature. The temperature of the section of polymer cladding is adjusted to cause a corresponding change in the phase of the laser light flowing through the waveguide core bounded by the polymer cladding to effect a desired switching or modulation of the laser light.

    摘要： An optically active composition (100) for optical applications has been identified. The optically active composition (100) can include at least one cyclic molecule having a nanocore (112) disposed within the cyclic molecule to form a filled ring (108). The composition (100) is optically transmissive for at least one photonic wavelength that would not otherwise be transmitted by the composition (100) if the nanocore were absent from the cyclic molecule. The cyclic molecule can be a carbon ring, an aromatic ring, or a heterocyclic ring. The filled ring (108) can be attached to a chiral molecule which is a repeat unit (102) in a polymeric backbone. A second filled ring (110) which causes the composition to be optically transmissive at a second wavelength also can be attached to the chiral molecule (102) as well. An electric field can be applied to the filled ring (108) to adjust the wavelength at which filled ring (108) is transmissive.
