摘要
Chalcogenide (As2S3) is a material with promising applications in integrated photonics. This material has the potential for low-threshold, compact, and high-coherence light sources. Our team has developed a chalcogenide-based distributed feedback (DFB) laser using a ridge polymer waveguide structure, incorporating a 500 nm As2S3 grating as the wavelength selective element. With precise engineering of the DFB laser structure, we have achieved single-mode lasing with an 18 nJ lasing threshold and a side mode suppression ratio (SMSR) of 28 dB. Additionally, we have found that the single-mode lasing persists over a wide range of pump power energy. To validate our experimental results, we performed a numerical simulation of the proposed structure, which confirmed experimental results.
