International Classification:

G02F 135

US Classification:

252582, 359328

Abstract:

Sterically stabilized second-order nonlinear optical chromophores and devices incorporating the same are embodied in a variety of chromophore materials. An exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a bridge structure therebetween, with the electron acceptor group being double bonded to the bridge structure. In a preferred embodiment, the bridge structure also includes at least one bulky side group. Another exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a ring-locked bridge structure between the electron donor group and the electron acceptor group. The bridge structure comprises, for example, two protected alicyclic rings or ring-locked trienone. Another exemplary preferred chromophore includes an electron donor group, a ring-locked tricyano electron acceptor group, and a bridge structure therebetween. In a preferred embodiment, the electron acceptor group comprises an isophorone structure.

US Classification:

385 1, 385 2, 385 40, 385 50

Abstract:

A system and method are disclosed for a rapidly tunable wavelength selective ring resonator. An embodiment of a voltage-tunable wavelength selective ring resonator includes a ring-shaped waveguide formed on a semiconductor substrate, an electro-optic cladding layer formed over the ring-shaped waveguide, and voltage applying means for applying a voltage across the electro-optic cladding layer. The ring-shaped waveguide is configured to propagate optical signals having predetermined resonant wavelengths, the electro-optic cladding layer has a voltage-controlled variable refractive index, and the means for applying is configured to apply a wavelength-specific control voltage to the electro-optic cladding layer. The wavelength-specific control voltage will shift or tune the predetermined resonant wavelengths for the ring-shaped waveguide.
