A hybrid integrated dual-parallel modulated DFB laser is experimentally demonstrated. Utilizing the proposed method, the nonlinear distortions of the DFB laser, including the second harmonic distortion (2HD) and the third-order intermodulation distortion are suppressed significantly. Comparing with the single modulated DFB laser, the 2HD is reduced by 8.6 dB and the spurious free dynamic range is increased from 87.2 dB•Hz 2/3 to 90.3 dB•Hz 2/3 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
