    摘要: A subwavelength terahertz (THz) switch using an artificially designed conductor metamaterial is discussed in this invention. Theoretically, slow-light EM wave propagating at THz speed imitates the strongly localized surface plasmon modes and henceforth is called Spoof Surface Plasmon Polariton (SSPP) mode in this invention. The SSPP mode of slow-light EM propagation can be easily tailored by changing the refractive index of the dielectric materials inside the metallic gap structure engineered as a periodic array of grooves. Thus, the incorporation of electro-optical material which has birefringence such as a nematic liquid crystal (N-LC) or multiple-refractive indices into the metallic gap leads to a highly compact and efficient terahertz switch being controlled by a low-voltage signal. The optimal design of the SSPP switch enabled by this novel method shows many interesting properties including 1) strong subwavelength localization; 2) relatively high extinction (On/Off switching) ratio; and 3) small damping attenuation. The THz dynamic switches can be used to construct linear switches, Y junction switches and Mach-Zehnder interferometers by using micromachining and other fabrication techniques.

    摘要: A plasmonic transistor device includes an electro-optic substrate and a conductive layer placed on said electro-optic substrate to establish an interface therebetween. The first conductive layer and electro-optics substrate are made of materials that are suitable for transmission of a surface plasmon along the interface. The conductive layer is further formed with a source input grating and a drain output grating, for establishing the surface plasmon. A means for varying the electro-optic substrate permittivity, such as a light source or voltage source, is connected to the electro-optic substrate. Selective manipulation of the varying means allows the user to selectively increase or decrease the substrate permittivity. Control of the substrate permittivity further allows the user to control surface plasmon propagation from the source input grating along the interface to a drain output grating, to achieve a transistor-like effect for the surface plasmon.

    摘要: A frequency-conversion method that uses a nonlinear optical process to transfer energy between a surface-plasmon (SP) wave that is guided along an electrically conducting strip and a light beam that is guided along an optical waveguide whose core is adjacent to the electrically conducting strip. A periodic structure spatially modulates the nonlinear susceptibility of the waveguide core with a spatial period that is related to a momentum mismatch in the nonlinear optical process. The spatial modulation provides quasi-phase matching for the SP wave and the light beam and enables efficient energy transfer between them.

    摘要: This invention provides fundamental science and novel device architectures for surface plasmon (SP)-based, complementary metal oxide semiconductor (CMOS)-compatible, optical elements such as modulators, couplers, and switches. The primary focus of the work is on waveguides based on an ultra-long-range surface plasmon (ULRSP) waveguide mode recently discovered by our team. This mode exists at the metal-dielectric interfaces in a silicon-oxide-metal-silicon layer structure. While initial work focuses on noble metals to support the ULRSP, our analysis shows Si processing-compatible metals such as Cu and Al can also be used. Our modeling has also shown that variation in the thickness of the oxide layer can be used to give unprecedented propagation lengths in such structures. Electrically-induced free carrier modulation of the dielectric constant in the Si adjacent to the oxide can modulate the waveguide properties allowing novel Si-compatible electro-optic devices to be created. These waveguides function as the “wiring” in new classes of optical chips. This invention also provides integration of ULRSP waveguides and switches with other optical elements to create entirely new classes of hybrid optoelectronic technologies for defense applications. These range from chip-based chemical agent detection to extremely high performance processors and even all-optical computations.
