A Novel Kind of Transverse Micro-Stack High-Power Diode Bars被引量：1
《Chinese Physics Letters》2008年第4期1284-1286,共3页张蕾 崔碧峰 李建军 郭伟玲 王智群 沈光地 
Supported by the National Basic Research Programme of China under Grant No 2006CB604902, the National Natural Science Foundation of China under Grant No 60506012.
Novel transverse micro-stack semiconductor laser bars are put forward to improve the output optical power of semiconductor laser bars at low injection current. More importantly, the novel laser bars have a coupled lar...

An Innovative Gas Sensor with On-Chip Reference Using Monolithic Twin Laser被引量：6
《Chinese Physics Letters》2007年第10期2839-2841,共3页张永刚 田招兵 张晓钧 顾溢 李爱珍 祝向荣 郑燕兰 刘盛 
An innovative gas sensor with on-chip reference using a monolithic twin laser is proposed. In this sensor a monolithic twin laser generates two closer laser beams with slight different wavelengths alternatively, one p...

Period-Doubling in 10 GHz Gain-Switched DFB Laser Diode
《Chinese Physics Letters》2007年第10期2852-2854,共3页伍剑 邱吉芳 林金桐 
Supported by the National Natural Science Foundation of China under Grant No 90401025, the Ministry of Education of China under Grant No NCET-04-0116 and 105036.
The distinct period doubling behaviour in a 10 GHz gain-switched （GS） DFB laser is experimentally investigated in frequency domain and in time domain. The period doubling occurs as the frequency of the rf driving si...

Gain Measurement and Anomalous Decrease of Peak Gain at Long Wavelength for InAs/GaAs Quantum-Dot Lasers
《Chinese Physics Letters》2007年第10期2984-2986,共3页肖金龙 黄永箴 杜云 赵欢 倪海桥 牛智川 
Supported by the National High Technology Development Program of China under Grant No 2003AA311070, and the National Natural Science Foundation of China under Grants Nos 60225011 and 60625405.
Mode gain spectrum is measured by the Fourier series expansion method for InAs/GaAs quantum-dot （QD） lasers with seven stacks of QDs at different injection currents. Gain spectra with distinctive peaks are observed ...

Self Mixing Fringes of Vertical-Cavity Surface-Emitting Lasers under Dual Reflector Feedback
《Chinese Physics Letters》2006年第12期3275-3277,共3页程翔 张书练 张连清 谈宜东 
Supported by the National Natural Science Foundation of China under Grant No 60438010.
The self-mixing fringes which shift due to every one-twentieth wavelength displacement of the target are observed. Taking advantage of the dual reflectors in the external cavity of lasers, the resolution of the sensor...

Simulation of Patterns and Qualitative Analysis of Pattern Rotation in an End-Pumped Nd：YVO4 Laser
《Chinese Physics Letters》2006年第11期2982-2984,共3页韩克祯 潘淑娣 范秀伟 黄海涛 何京良 
Supported by the National Natural Science Foundation of China under Grant Nos 10534020 and 60478009.
We simulate some laser output patterns observed in our previous experiment employing superposition of Laguerre- Gaussian modes. The rotating pattern is qualitatively analysed from the point of contemporary spatial bur...

Exact Solution to Rate Equation with Time-Dependent Coefficients： Its Application in InGaAsP Lasers
《Chinese Physics Letters》2006年第3期535-538,共4页王刚 罗斌 潘炜 吴绍全 侯邦品 
Supported in part by the Specialized Research Fund for the Doctoral Program of Higher Education （SIZFDP） under Grant No 20030613007, the Natural Science Foundation of the Committee of Education of Sichuan Province under Grant No 2003A078, and the Funds for Major Basic Research Project of Sichuan Province under Grant No 02GY029-188.
By using the algebraic dynamics method, we obtain exact analytical solutions of rate equations with time-dependent coefficients, which might present an effective description of the physical mechanism of the practical ...
