Currently, there are no analytical formulas or ordinary differential equations (ODEs) to investigate the higher order statistics for the gain variations in fiber parametric amplifiers (FOPAs) with dispersion fluctuation. This is mainly due to the ted

The higher order (such as the 2nd order and the 4th order) moments of the Mueller matrix elements are important to estimate the polarization mode dispersion (PMD) induced power fluctuations for the forward propagation and the backward scattered signa

In this paper, the capacity of the free space optical communication system employing the general Laguerre Gaussian (LG) modes under random atmosphere turbulence is studied. A coupled mode theory is used to derive the coupled equations to evaluate the

In this letter, we study a dual-core fiber optical parametric amplifier with its pumps having the arbitrary power and phase distributions. A full analytical model is derived for such a general pumping scheme based on the rotating wave approximation,

In this letter, a new initialization procedure is proposed for channel equalization in the mode division multiplexing (MDM) systems. The initialization procedure is based on the orthogonal matching pursuit (OMP) algorithm. With the proposed method, i

In this paper, we propose a novel tunable unitary transformer, which can achieve arbitrary discrete unitary transforms. The unitary transformer is composed of multiple sections of multi-core fibers with closely aligned coupled cores. Phase shifters a

In this paper, an optimal mode set is proposed to maximize the receiving power for free space transmission under atmosphere turbulence with transmitter/receiver aperture size constraint. The optimal beam profiles are evaluated through eigenmode analy

This paper analyzes the capacity of the free space coherent optical MIMO transmission system. Two scenarios are considered (i.e., with and without the adaptive optics compensation). It is generally accepted that the adaptive optics compensation can s
