Excimer laser based crystallization has become a workhorse in preparing poly-Si films for the manufacture of back plates for active matrix liquid crystal displays. Alternative laser techniques applyin...
Demonstration of a full duplex PON featuring 2.5 Gbps Sub Carrier Multiplexing downstream and 1.25 Gbps upstream with colourless ONU and simple optics
duplex PON featuring Carrier Multiplexing downstream colourless ONU optics
2015/8/3
We demonstrate a full-duplex DPSK SCM PON operating at 2.5Gbps/1.25Gbps bitrates, with RSOA ONU and simplified scheme. It achieves low sensitivity and is implemented with low-cost components.
Fiber Optics Implementation of Single Quantum Coin Tossing
Fiber Optics Implementation Single Quantum Coin Tossing
2015/7/30
We report an all fiber optics experimental implementation of quantum coin tossing using attenuated laser pulses at 1550nm in which a single coin is tossed whose randomness is higher than achievable by...
An adaptive optics imaging system is introduced in this paper. A high-resolution liquid crystal on silicon (LCOS) device was used as a phaseonly wavefront corrector instead of a conversional deformabl...
Based on a simple eye model system, a high resolution adaptive optics retina imaging system was built to demonstrate the availability of using liquid crystal devices as a wave-front corrector for both...
