Accurate Dynamic Model of DFB lasers
Efficient and reliable models for semiconductor distributed feedback (DFB) lasers design and optimization are highly desirable. An innovative dynamic model for accurate simulations of DFB lasers is proposed in this paper. The developed algorithm is based on a system of coupled partial differential equations which is solved by the finite element method (FEM). No approximation is assumed and obta...
متن کاملQuarter-Wave-Shifted DFB Lasers
High-coupling (KL = 3.0) phase-shifted DFB lasers are studied using a transmission-line laser model (TLLM), which includes spatial hole burning (SHB), the material gain spectrum, refractive index dependence on carrier concentration, and random spontaneous emission. Good agreement for CW spectra is shown with other models and experimental results. Dynamic simulations of laser transients show SHB...
متن کاملInvestigation of High Linearity DFB Lasers for Analog Communications
High-linearity, low-noise DFB lasers are necessary for analog optical communications, including subcarrier multiplexed systems, wireless personal communication systems (PCS) service and phased array radar. In this thesis, we examine the dynamic range and distortion for a Fujitsu DFB laser. We extract parameters from the device and use these parameters to simulate the distortion characteristics....
متن کاملSimple rate-equation model for two-photon lasers.
We present a rate-equation model for two-photon lasers that, despite its simplicity, captures the essential physics of their behavior and affords an intuitive understanding of their novel threshold and stability behavior. We use the model to investigate the steady-state behavior of the laser, explore the stability of the steady-state solutions, and predict the injected pulse strength needed to ...
متن کاملLinewidth and Phase Noise Characteristics of DFB Fibre Lasers
Short cavity single frequency fiber lasers have been a topic of continued interest since the early work of Ball et al on Er-doped DBR (distributed Bragg reflector) fiber lasers. Their size, simplicity, ease of fabrication, compatibility to transmission fiber and optical emission characteristics make them attractive for a number of applications, particularly in the sensing area. However, there h...
