摘要： An integrated optical filter device that is tunable with a narrow linewidth and fast operation, and that can be configured to perform a number of filtering functions, including pass-through and multi-channel drop functions, redirecting optical radiation of different wavelengths into different optical channels. The filter device is easy to fabricate inexpensively and reliably using existing technology and is compact and more densely packed than devices produced by the prior art, even for low refractive index materials, in that it uses substantially straight rather than curved strip optical waveguides. Wavelength tuning can be accomplished by means of a number of alternative control arrangements and configurations.

摘要： An electro-optical modulator includes an optical waveguide for carrying an optical carrier wave and a control waveguide for carrying a control wave. The optical waveguide includes a cladding layer and a core. The two waveguides are collinear and overlap in an interaction region so that the refractive index of the optical waveguide responds to electric fields generated by the control wave in the interaction region. The refractive index of the cladding layer at the control wave's wavelength is higher than the refractive index of the core at the optical carrier wave's wavelength.

摘要： A multistage Mach-Zehnder interferometer type optical circuit including any number of symmetrical Mach-Zehnder interferometers and any number of asymmetrical Mach-Zehnder interferometers connected in cascade. In the optical circuit, low coherence light is used first to obtain individual phase control conditions of the symmetrical Mach-Zehnder interferometers without being affected by the asymmetrical Mach-Zehnder interferometers. Second, phase control conditions of the individual asymmetrical Mach-Zehnder interferometers are obtained by controlling the symmetrical Mach-Zehnder interferometers based on the first phase control conditions. Finally, the characteristic adjustment of the whole multistage Mach-Zehnder interferometer type optical circuit is carried out by controlling all the interferometers based on the phase control conditions of both the symmetrical Mach-Zehnder interferometers and asymmetrical Mach-Zehnder interferometers and setting the phase shift amounts of the individual interferometers at appropriate values.

摘要： A new electro-optic (EO) phase modulator constructed from a combination of a low-loss passive polymer waveguide and a self-assembled chromophore superlattice (SAS) with an intrinsically polar microstructure. In contrast to typical polymer-based modulators, the present invention utilizes a siloxane SA methodology that enables the acentric alignment of constituent chromophores during film growth without the need for post-deposition electric field poling. The guiding layer is constructed of the SAS and the glassy polymer Cyclotenenull. The use of SiO2, Cytopnull and Cyclotenenull glassy polymers, results in a straightforward device fabrication process that is compatible with the thermally and photochemically robust SAS. Thus, nanoscale control of the film architecture results in greatly simplified macroscopic device fabrication. The present invention provides a SAS-based electro-optic modulator demonstrating excellent electro-optic response properties and a null phase shift.

摘要： The present invention relates to an optical modulator including an optical waveguide, and at least one CPW-to-CPS transition. The CPW segments include a hot electrode; and a ground plane disposed on each side of the hot electrode, and they share a ground plane. The CPS segment extends along an interaction length of the modulator. In one embodiment, two driving signals are applied so that the modulator operates as a dual-drive modulator. In another embodiment, a domain-inverted region is formed in a substrate of the dual-drive modulator to overlap with one arm of the optical waveguide (MZI) and invert a sign of a phase shift induced in that arm. Finally, a fixed chirp can be introduced into the dual-drive modulator by asymmetrically positioning the interferometer arms into gaps of the CPW segments with respect to the hot electrode, and by employing unequal width gaps in the CPW segments.
