Experimental demonstration of the three phase shifted DFB semiconductor laser based on Reconstruction-Equivalent-Chirp technique.
TL;DR: A three phase shifted (3PS) distributed feedback (DFB) semiconductor laser based on Reconstruction-Equivalent-Chirp (REC) technique is experimentally demonstrated for the first time and exhibits its good single longitudinal mode (SLM) operation even at high bias current and surrounding temperature.
Journal ArticleDOI

Yunshan Zhang,Lianyan Li,Yating Zhou,Guowang Zhao,Yuechun Shi,Jilin Zheng,Zhike Zhang,Yu Liu,Linjie Zou,Yuke Zhou,Yinchao Du,Xiangfei Chen +11 more
TL;DR: A monolithic optical injection-locked (MOIL) DFB laser with large stable injection locking range is experimentally demonstrated using the side-mode injection locking technique and the low-frequency roll-off in the MOIL D FB laser is suppressed significantly.
Journal ArticleDOI
A Cascaded Tunable DFB Semiconductor Laser With Compact Structure
TL;DR: In this article, a compact cascaded tunable distributed feedback semiconductor laser is proposed and theoretically analyzed, where each laser section (LS) is formed by two adjacent grating sections (GSs) with slightly different Bragg wavelengths and a π phase shift in the joint between them.
