In this paper, a detailed carrier dynamics model for quantum well lasers is used to study the modulation bandwidth of the directly modulated strained-layer multiple quantum well (SL-MQW) laser. The active region of the directly modulated laser (DML)

In this paper, we propose a DFB laser with a horn ridge waveguide (HRW) to suppress the longitudinal spatial hole burning (LSHB) effect in the lasers cavity, thus to reduce the rolloff at low frequency. The simulation result shows that HRW DFB lasers

Take Runge-Kutta exponential time differencing finite-difference time-domain (RKETD-FDTD) method, simulate numerically, analyze the transmission properties of terahertz (THz) wave in the non-magnetized plasma medium, and conclude the regulations of T

A self-corrected sensing method is proposed and studied using a surface plasmon resonance scheme with metal–dielectric–metal (MDM) structure. The surface plasmon wave (SPW) modes supported by the MDM structure couple further to the SPW at sensing

Plasma photonic crystals are artificially periodic structures, which are composed of plasmas and dielectric structures. In this paper, the Runge–Kutta exponential time differencing (RKETD) finite-difference time-domain (FDTD) method is applied to s

Among a variety of techniques for broadband access, the infrastructure based on Passive Optical Network (PON) is one of the most viable solutions. In 10- and 40-Gigabit capable PON, the downstream wavelength in optical line terminals (OLTs) has been

In this paper, a z-axis displacement sensor based on Total-Internal Reflection and Surface Plasmon Resonance in heterodyne interferometry is proposed. The sensing unit is composed of a parallelogram prism, i.e. elongated prism, and a displacement pro

A full physics based model has been exploited to systematically study the modulation bandwidth of the directly modulated strained-layer multiple quantum well (SL-MQW) laser. The major parameters of the active region are optimized to achieve the maxim
