A voltage-controlled birefringent cell based on ceramic PMN-PT material is used to enable fast intensity modulation of femtosecond laser pulses in the 800 nm wavelength window. The birefringent cell based on a PMN-PT compound has comparatively high electro-optic response, allowing for a short interaction length of 3 mm and thus very small size, low attenuation of 0.16 dB, and negligible broaden...

In this study, acoustic emissions (AEs) were detected through a variety of different flooring materials using a fibre Bragg grating (FBG). The AEs were generated using a low velocity impact test, and by footstep. The acoustic vibrations cause a strain in the optical fibre, and hence alter the wavelength reflected by the FBG. This strain induced wavelength shift can then easily be detected by co...

Spatial diffusion reflection (DR) measurements of gold nanorods (GNR) were recently suggested as a simple and highly sensitive non-invasive and non-ionizing method for real-time cancer detection. In this paper we demonstrate that wavelength dependent DR measurements enable the spectral red-shift observation of highly concentrated GNR. By conjugating targeting moieties to the GNR, large density ...

We achieved first dynamic all-optical signal processing with a bandgap-engineered MZI SOA all-optical switch. The wide-gap Selective Area Growth (SAG) technique was used to provide multi-bandgap materials with a single step epitaxy. The maximum photoluminescence (PL) peak shift obtained between the active region and the passive region was 192 nm. The static current switching with the fabricated...

Abstract Cubic phase CsPbBr 3 perovskite nanocrystals (PNCs) was prepared by a high-temperature hot-injection method. The high photoluminescence quantum yield (PLQY) of as-prepared PNCs 87%, which can be used for the determination chloridion in domestic water samples based on their wavelength-shift characteristics via halide exchange. proposal approach reveals linear correlation ranged from 10 ...

All-optical code conversion of 10 Gb/s BPSK codes without wavelength-shift by use of cross-phase modulation in an optical fiber for optical code division multiplexing networks is proposed and experimentally demonstrated.
