Low Harmonic Distortion DFB Laser for Broadband Analog Applications
IEEE Photonics Technology Letters(2020)
摘要
$1.35~\mu $ m AlGaInAs/InP DFB lasers with low harmonic distortion and high frequency response bandwidth have been demonstrated for broadband analog applications. By optimizing active layers and setting Bragg wavelength 10 nm blue shifted of the gain peak wavelength, the device has a threshold current of 8.5 mA, 3-dB frequency response bandwidth of 21 GHz at 60 mA and 28GHz at 90 mA, second harmo...
