Analysis of TDECQ Dependence on Skew and Extinction Ratio with 106-Gb/s PAM-4 modulation of Directly Modulated Submicron Ridge Localized Buried Heterostructure Lasers

Not Accessible

Your library or personal account may give you access


The importance of high relaxation oscillation frequency to obtain superior 106-Gb/s PAM-4 waveforms was revealed for SR-LBH lasers. In addition, clear 56-Gb/s NRZ eye openings were first demonstrated up to 85°C using SR-LBH laser.
