Silicon-organic hybrid integrated devices have emerging applications ranging from high-speed optical interconnects to photonic electromagnetic-field sensors. Silicon slot photonic crystal waveguides (PCWs) filled with electro-optic (EO) polymers comb

A low loss and high sensitivity X-band RF sensor based on electro-optic (EO) polymer filled silicon slot photonic crystal waveguides (PCW) and bowtie antenna is proposed. By taking advantage of the slow light enhancementt in the PCW(>20X), large EO c

In this work, we design, fabricate and characterize a compact, broadband and highly sensitive integrated photonic electromagnetic field sensor based on a silicon-organic hybrid modulator driven by a bowtie antenna. The large electro-optic (EO) coeffi

A carboxylated polysulfone (C‐PSF) was reacted with 3‐(glycidoxypropyl)trimethoxysilane (GPS) in a sol–gel reaction to form hybrid networks. Specifically, GPS was grafted to the C‐PSF chains at their epoxy ends by ring‐opening reactions and

Moisture diffusion in a BMI resin has been investigated by submerging thin specimens in water. The weight gain of the neat resin deviates significantly from Fick's law in that the uptake continues to slowly increase over an extended time scale. A two

The buckling of a fiber with a fibrillar microstructure is examined in light of all possible buckling modes. Parametric studies are done at variously assumed morphological levels, from a fibril down to a molecular chain, and it is shown that the buck

The high degree of electron delocalization in heterocyclic aromatic molecules makes this class of chemistry ideal for hyperpolarizability and NLO (nonlinear optics) polymer developments. This type of polymer is usually insoluble in common solvents an

Benzobisthiazole polymers containing mono-, bi-, and terthiophene moieties were synthesized through polycondensation in polyphosphoric acid of 2,5-diamino-1,4-benzenedithiol dihydrochloride with thiophene-2,5-dicarboxylic acid, 2,2′-bithiophene-5,5

Dynamic and tensile mechanical properties of a series of graft rigid-rod copolymers were studied. The copolymers were single-component rigid-rod molecular composites consisting of a rigid-rod poly( p -phenylenebenzobisthiazole) backbone grafted with
