Transforming information from spin encoding to route encoding

Spin (polarization) is widely used in free-space optics, while in photonic integrated circuits (PICs), information is usually encoded in optical route. So a practical way to connect these two encoding methods is necessary for information communication. In this letter, an encoding convertor is designed to connect spin encoding and route encoding. Finite element method is used to calculate the conve...
Editorial for Focus Issue on Optical 3D Display and Imaging

With the impressive progress of flat panel display technologies, the three-dimensional (3D) display and imaging technologies have attracted much attention in recent years as they can provide ultimate realistic views to us. Hence we designed a focus issue intended to introduce recent optical researches in this field, especially the works by some distinguished research groups.This focus issue includ...
Iterative sparse reconstruction of spectral domain OCT signal

We propose and study an iterative sparse reconstruction for Fourier domain optical coherence tomography (FD OCT) image by solving a constrained optimization problem that minimizes L-1 norm. Our method takes the spectral shape of the OCT light source into consideration in the iterative image reconstruction procedure that allows deconvolution of the axial point spread function from the blurred image...
Temperature and metal composition dependence of lateral photovoltaic effect in Al-Alq3/SiO2/Si structures

A series of Alx-(Alq3)1?x granular films is prepared on Si wafer with native oxide layer using co-evaporation
technique. Large lateral photovoltaic effect (LPE) is observed, with an optimal LPV sensitivity of 75
mV/mm in x = 0.35 sample. The dependence of LPE on temperature and Al composition is investigated,
and the possible mechanism is discussed.
