An InGaAs Vertical-Cavity Surface-Emitting Laser Emitting at 1130 nm for Silicon Photonics Application

Photonics
A highly strained InGaAs quantum well (QW) vertical-cavity surface-emitting laser (VCSEL) with low threshold current density, high efficiency and output power emissions around 1130 nm was grown by MOCVD. Its static characteristics at room temperature and

Research on the reliability of light power and intensity of current model of Vertical Cavity Surface Emitting Laser

上海师范大学学报. 自然科学版, 2018
We study the reliability of light power and intensity of current (L-I) model of Vertical Cavity Surface Emitting Laser (VCSEL). We use the methods of nonlinear least squares, polynomial fitting and numerical calculation to estimate the model of ...

Fundamentals and applications of spatial dissipative solitons in photonic devices : [Chapter 6]

, 2009
We review the properties of optical spatial dissipative solitons (SDS). These are stable, self‐localized optical excitations sitting on a uniform, or quasi‐uniform, background in a dissipative environment like a nonlinear optical cavity.

Frequency and phase locking of laser cavity solitons

, 2012
Self-localized states or dissipative solitons have the freedom of translation in systems with a homogeneous background. When compared to cavity solitons in coherently driven nonlinear optical systems, laser cavity solitons have the additional freedom of ...
