With reasonable simplified polarization modelling for fiber channel, we propose a window-split frequency domain Kalman scheme to equalize the signal distortion induced by combined large DGD (more than 200ps) and fast RSOP (up to 2Mrad/s).

Gradient echo memory is the most efficient quantum memory protocol to date. Recent additions of machine learning and compatible single photons can raise its performance and the possibility of using it as a quantum gate.

Different lasing modes including in-phase modes, out-of-phase modes and special mixture modes are obtained from Ht-implantation-defined coherently coupled VCSEL arrays by engineering the interelement spacings between elements. The simulated far-field patterns match the experiments well.

We propose the use of through-focus scanning optical fluorescence microscopy for marine phytoplankton count. The phytoplankton in a seawater container of 20 ⨯ 20 ⨯ 20 mm is excited by a LED of 435 nm and the fluorescence emission from the phytoplankton over 656 nm is imaged into the image detector (CCD)through an objective lens and a tube lens. The proposed method stacks the sectioned image of the sea water in the container as it optically moves the image plane vertically along the optical axis by moving the tube lens. We built a prototype and it was demonstrated to count the phytoplankton of 1cc (10⨯10⨯10mm)volume with a spatial resolution less than 10 μm in one second.
