Our universal QAM/PSK modulator core is aimed at broadband point-to-point and point-to-multipoint applications and supports QAM orders from 2 (BPSK) to 256. It is compatible with the IEEE 802.16.x ...

Abstract: In this letter, we conduct an experiment of quantum noise stream cipher scheme based on 3-channel-QAM mapping and DFTs-OFDM in optical back-to-back and 160km standard single mode fiber. The ...

Our universal QAM Demodulator core is aimed at broadband point-to-point and point-to-multipoint applications and supports QAM orders from 2 (BPSK) to 256. Integrates with Commsonics QAM ...

Abstract: The self-coherent scheme is attractive for free space optical communications (FSO) due to the higher oscillator-signal ... which transmits independent quadrature amplitude modulation (QAM) ...

However, the mechanisms underlying their function have remained poorly understood. In this study, we combine experimental and computational approaches to show that ligand binding alone is not ...

We review basic principles of modern optical magnetometers, discuss fundamental limitations on their performance, and describe recently explored applications for dynamical measurements of ...

Optic neuritis (ON) is an inflammation that damages your optic nerve. It can cause vision loss and pain when you move your eyes. As the inflammation goes away, your symptoms usually get better ...

Now that looks set to change thanks to the work of Gordon Li and Midya Parto at the California Institute of Technology in Pasadena, and colleagues, who have designed and tested an all-optical computer ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...
