Numerical Simulation of External-Cavity Distributed Feedback Semiconductor Laser
《Optics and Photonics Journal》2023年第6期109-118,共10页Tianyu Guan Chaoze Zhang Yuqin Mao Ligang Huang Tao Zhu 
We propose a theoretical model to describe external-cavity distributed feedback semiconductor lasers and investigate the impact of the number of external feedback points on linewidth and side-mode suppression ratio th...

Coherent Parameter Measurement Based on Partial Coherent Envelope Demodulation
《Optics and Photonics Journal》2023年第6期133-139,共7页Chaoze Zhang Laiyang Dang Tianyu Guan Yuqin Mao Ligang Huang Tao Zhu 
The key parameters of laser energy concentration and coherence can be characterized by laser linewidth, which determines the detection range, measurement resolution and signal-to-noise ratio of laser precision measure...

Investigation of Tolerable Laser Linewidth for Different Modulation Formats in CO-OFDM Systems被引量:1
《Optics and Photonics Journal》2017年第5期92-100,共9页Divya Dhawan Neena Gupta 
The ideal behavior of communication system requires a single frequency carrier. In optical communication system, light is used as a carrier. Practical laser source has a finite linewidth due to variations in the frequ...
