In this paper, we analyze a traveling wave electrode as it drives a high-speed electro-optic (EO) polymer/TiO2 multilayer slot waveguide modulator by simulation. To enhance its mode confinement, the EO polymer is clipped by TiO2 slot waveguide films,

Sol-gels are an important material class, as they provide easy modification of material properties, good processability and are easy to synthesize. In general, an electro-optic (EO) modulator transforms an electrical signal into an optical signal. Th

Polymers have long been known to boast extraordinary properties that make them useful in a broad range of applications. Since the German organic scientist Hermann Staudinger demonstrated the existence of macromolecules, which he called polymers, in t

We demonstrate that the electro-optic (EO) modulation response linearly decreases (dB scale) with respect to the modulating frequency, with an extremely small drop of less than 2 dB, up to a limit of 67 GHz, as measured by an optical component analyz

We have presented a alternative soft process named nanolayer transfer (NLT), to fabricate hybrid electro-optic polymer/TiO2 vertical slot waveguide modulators. We have transfered successfully a 100 nm thick TiO2 line pattern layer on sol-gel silica c

Bragg grating structure in a sol-gel silica waveguide is fabricated on the basis of nanoimprint lithography for biophotonic applications. The process realizes nonstandardized lithography in sol-gel silica at a high resolution for a relatively large a

We analyze the advantages of an electro-optic (EO) polymer/TiO2 vertical slot waveguide modulator based on a low-index EO polymer (SEO125). This modulator can realize a lower half-wave voltage (Vπ)-electrode length (Le) product (VπLe) when compared

In order to minimize the damage from viral epidemics, early detection of the causative agent of a viral epidemic and prevention of its immediate spread are urgent social demands. Therefore, in this study, we evaluated the utility of a Mach-Zehnder-ty
