 Abstract—Optical interconnects play a key role in the implementation of high-speed short-reach communication links within high-performance electronic systems. Multimode polymer waveguides in particular are strong candidates for use in passive optical backplanes as they can be cost-effectively integrated onto standard PCBs. Various optical backplanes using this technology and featuring a large...

We describe development of semiconductor X-band high-power RF switches. The target applications are high-power RF pulse compression systems for future linear colliders. We describe the design methodology of the architecture of the whole switch systems. We present the scaling law that governs the relation between power handling capability and number of elements. We designed and built several act...

We report on the first demonstration of a fully suspended 10 m Fabry-Perot cavity incorporating a waveguide grating as the coupling mirror. The cavity was kept on resonance by reading out the length fluctuations via the Pound-Drever-Hall method and employing feedback to the laser frequency. From the achieved finesse of 790 the grating reflectivity was determined to exceed 99.2% at the laser wav...

We theoretically investigate the possible increase of the second harmonic generation (SHG) efficiency in silicon compatible waveguides by considering an asymmetrical plasmonic slot waveguide geometry and a χ((2)) nonlinear polymer infiltrating the slot. The needed phase matching condition is satisfied between the fundamental waveguide mode at the fundamental frequency (FF) and second-order wave...

An optimal design for an extra-low loss buried waveguide Y-branch splitter is presented over a broadband wavelength range from 1500~1600 nm. A tapered multimode waveguide section, earlier used to reduce the excess loss, is optimized when the light distribution at the end of the multimode waveguide section is matched to the profile of the symmetric supermode for the structure of the two branchin...

Integrated Al2O3:Er 3+ channel waveguide ring lasers were realized on thermally oxidized silicon substrates. High pump power coupling intoand low output power coupling fromthe ring is achieved in a straightforward design. Wavelength selection in the range 1532 to 1557 nm was demonstrated by varying the length of the output coupler from the ring. Keywords—waveguide laser; ring laser; erbium-dope...

A design of microfluidic devices is presented to integrate single-mode, liquid-core waveguides with microfluidic channels that generate and deliver disklike emulsion microdroplet cavities doped with an organic dye. The microcavity modes can be directly coupled to the liquid waveguide. Cavity-enhanced spontaneous emission was observed at the waveguide with low pump pulse energy.

We have designed and fabricated a novel 90 bend in a photonic crystal waveguide. The design was obtained using topology optimization and the fabricated waveguide displays a bend loss for transverse-electric-polarized light of less than 1 dB per bend in a 200-nm wavelength range.

We design and numerically simulate a photonic crystal waveguide cavity with a nanoslot structure for single nanoparticle trapping. A 135x enhancement of optical gradient trapping force compared to plain waveguide trapping devices has been achieved. ©2009 Optical Society of America OCIS codes: (350.4855) Optical tweezers or optical manipulation; (350.4238) Nanophotonics and photonic crystals
