Abstract
The hybrid integrated dual-parallel modulated DFB laser is designed and fabricated to suppress the nonlinear distortion. A reduction of about 7.4 dB of the third-order intermodulation distortion (IMD3) and an increase of 5 dB of the spurious free dynamic range (SFDR) compared to the single DFB laser are achieved.
