We experimentally demonstrate real-time C-band transmissions with up to 29 dB optical budget after 25 km propagation at 20 Gbit/s and 25 Gbit/s. Our solution uses pre-equalization and electro-optical components dedicaded for 10 Gbit/s transmissions.

We use an ultrafast electro-optic dual comb interferometer to perform single-point vibrometry on the submillisecond time scale. As an example, we resolve the vibration of an ultrasound speaker driven at 50 kHz, achieving a sub-nanometer axial resolution through a measurement of the optical phase carrier. OCIS codes: (320.7100) Ultrafast measurements; (120.6200); Spectrometers and spectroscopic ...

A new microphotonic mm-wave receiver architecture with direct electrical-to-optical conversion is presented. The receiver uses high-Q RF and microphotonic electro-optic resonator components which are operated in simultaneous resonance. Initial results demonstrating modulation of an optical carrier at RF in the mm-wave range are reported .

The absorption cross section of colloidal quantum dots in close-packed monolayers shows a 4 (CdSe) to 5-fold (PbS) enhancement compared to quantum dots in a dilute dispersion. Quantitative agreement is demonstrated between the value and the size dependence of the enhancement and theoretical model predictions based on dipolar coupling between neighboring quantum dots. This collective optical beh...

Optical modulators (OMs) are a key device in modern optical systems. Due to its unique optical properties, graphene has been recently utilized in the fabrication of optical modulators, which promise high performance such as broadband response, high modulation speed, and high modulation depth. In this paper, the latest experimental and theoretical demonstrations of graphene optical modulators (G...

Multiple-layer perovskite Pb0.91La0.09Zr0.65Ti0.35O3/SrTiO3 (PLZT/STO) heterostructures have been grown by pulsed laser deposition (PLD) on (001) MgO/GaAs substrates. The perovskite layers are single phase with 35nm RMS roughness on the top surface. Electrically induced birefringence in the PLZT layers, resulted in both optical phase and optical amplitude modulation. The application of an elect...

We propose a new class of nanoscale electro-optical traps for neutral atoms. A prototype is the toroidal trap created by a suspended, charged carbon nanotube decorated with a silver nanosphere dimer. An illuminating laser field, blue detuned from an atomic resonance frequency, is strongly focused by plasmons induced in the dimer and generates both a repulsive potential barrier near the nanostru...

Single λ-DNA molecules are detected on a nanopore-gated optofluidic chip electrically and optically. Statistical variations in the single particle trajectories are used to predict the intensity distribution of the fluorescence signals.

All-Optical signal processing and routing avoid the optical-to-electrical and electrical-to-optical conversions and thus eliminates the bandwidth constrains set by conventional electronics technologies. It will form key building blocks for the next generation ultra-high speed and dynamic multi-casting optical networks. Polymer waveguide based photonics integrated circuits are promising in achie...
