Silica/electro-optic Polymer Optical Modulator for Mmw Receiving (preprint)
نویسندگان
چکیده
A silica/electro-optic (EO) polymer phase modulator is proposed for millimeter-wave (MMW) radiation receiver with the use of a bowtie antenna. Waveguide design optimization is presented for a waveguide with an EO polymer core and silica/solgel cladding. Electrode effects on the insertion loss and poling efficiency are also analyzed and conditions for low-loss and high poling efficiency established. The bowtie antenna is simulated and shows a broadband response with a maximum at SGHz and a 3dB-bandwidth of approximately 12GHz. A fiber splicing technique is presented that reduces coupling loss between SMF -28 and the waveguide. Experimental results for a fabricated device with MMW-response between 10-14GHz are shown with carrier to first sideband intensity difference of up to -36dB.

Mesoporous sol-gel silica cladding for hybrid TiO2/electro-optic polymer waveguide modulators.
We report the efficient poling of an electro-optic (EO) polymer in a hybrid TiO(2)/electro-optic polymer multilayer waveguide modulator on mesoporous sol-gel silica cladding. The mesoporous sol-gel silica has nanometer-sized pores and a low refractive index of 1.24, which improves mode confinement in the 400-nm-thick EO polymer film in the modulators and prevents optical absorption from the low...
متن کاملPolymeric Electro-optic Modulators: From Chromophore Design to Integration with Semiconductor Very Large Scale Integration Electronics and Silica Fiber Optics
Chromophores with optimized second-order optical nonlinearity to optical loss ratios are synthesized, poled with an electrical field, and coupled into hardened polymer matrixes. Acentric order, which is necessary for electro-optic activity, is optimized by the consideration of chromophore-chromophore electrostatic interactions as well as chromophore-poling field interactions and thermal collisi...

متن کاملSol-Gel Material-Enabled Electro-Optic Polymer Modulators
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. The incoming electrical signal is most commonly information encoded in a voltage change. This voltage change is then transformed into either a phase ...
متن کاملSurface-normal plasmonic modulator using sub-wavelength metal grating on electro-optic polymer thin film
In this work, we present the design, fabrication, and characterization of a surface-normal plasmonic modulator using sub-wavelength metal grating. The device consists of a 1.77 μm efficiently poled electro-optic polymer film, which is sandwiched between a plasmonic grating and an indium–tin oxide film. A strong Fano resonance with a sharp plasmonic bandgap at 1522 nm wavelength was observed and...
