Mode-division multiplexing has emerged as a promising route for increasing transmission capacity while maintaining the same level of on-chip integration. Despite large number mode converters and multiplexers reported silicon-on-insulator platform, scaling multiplexed modes is still critical challenge. In this paper, we present novel three-mode architecture based on multimode interference couple...

A single-particle entangled state can be generated by illuminating a beam splitter with a single photon. Quantum teleportation utilizing such a single-particle entangled state can be successfully achieved with a simple setup consisting only of linear optical devices such as beam splitters and phase shifters. Application of the locality assumption to a single-particle entangled state leads to Be...

Silicon-on-insulator technology offers solutions to the higher-performance and lower-power dilemma Digital Systems: New two-antenna handset technology improves CDMA network performance Tx/Rx: Making phase shifters affordable for widespread commercial electronically scanned antenna arrays Mixed Signal: High-speed digital and mixed-signal ICs using advanced indium phosphide heterojunction bipolar...

Communications wavelength waveguide mode conversion is demonstrated in an irregular metal-walled structure that was designed by using multiresolution optimization. Strong scatter and a large number of degrees of freedom allowed high-efficiency conversion in a device having a length of just a few wavelengths. The fabrication approach draws on standard semiconductor processing. Mode-selective ref...

A topology for a 3-dB broadband and small-size ring coupler is proposed. It consists of fully-distributed Composite Right-/Left-Handed phase shifters and a Lange coupler. For the fabricated coupler, the frequency bandwidth is one octave, centered on 1.5GHz, while the footprint area is reduced to 25%, compared to the conventional ring coupler topology. The experimental results are in good agreem...
