A novel 1×4 reconfigurable optical splitter/combiner structure based on Opto-VLSI processor and 4-f imaging system with high resolution is proposed and experimentally demonstrated. By uploading optimized multicasting phase holograms onto the software-driven Opto-VLSI processor, an input optical signal is dynamically split into different output fiber ports with user-defined splitting ratios. Als...
We report guided-light opto-mechanical sensing of the mechanical vibrations of a toroidal-lipped SiO2 GOBLiT. An optical quality factor of 1.7x10 allowed us to measure mechanical vibrations of the GOBLiT with mechanical quality factor 206 in air for the n=2 degenerate wineglass mode. Light was coupled into the resonator via a tapered optical fiber and used to sense mechanical motion of the GOBL...
Alluvial fans are one of the most important of types of geomorphic landforms in mountainous regions, especially in dry and semi-dry region, which flow processes create them with reducing the slope and opening the valley after leaving the mountain.This study investigate the effects of geographic directions on the dimensions of alluvial fans in down streams in Shirkouh Mountain in the central par...
Optogenetics has taken biomedical research by storm. The power and precision at which light-gated ion channels control cellular excitability in diverse biological systems has convinced researchers of an optical future. Growing interest in optical methods has sparked the development of multiple new optogenetic tools, which allow precise control of numerous cellular processes. Among these new too...
Advances in femtosecond lasers and laser stabilization have led to the development of sources of ultrafast optical pulse trains that show jitter on the level of a few femtoseconds over tens of milliseconds and over seconds if referenced to atomic frequency standards. These low jitter sources can be used to perform opto-electronic analog to digital conversion that overcomes the bottleneck set by...
