High speed InP lasers have been developed for 400Gbit/s interconnections. Electro-absorption modulator integrated DFB lasers were demonstrated for 106-Gbit/s PAM4 with 0.9 Vpp from 20 to 85°C. 106-Gbit/s PAM4 eye-openings were obtained using directl

53-Gbaud EA-DFB lasers—with four wavelengths in the 1500-nm region—for 800-GbE applications were developed. They demonstrated uncooled 53-Gbaud PAM4 operation with a TDECQ of lower than 2.5 dB over a wide temperature from 20 to 85°C.

We have developed high speed Electro-Absorption modulator integrated DFB (EA/DFB) lasers and directly modulated DFB lasers for 400 GbE applications. An uncooled type $1.3-\boldsymbol{\mu} \mathbf{m}$ EA/DFB laser was demonstrated for 53-Gbaud PAM4 op

Uncooled 53-Gbaud PAM4 operation of $1.3-\mu \text{m}$ electro-absorption modulator integrated DFB laser was demonstrated with 0.9 Vpp for the first time. We obtained extinction ratio of more than 4.9 dB and TDECQ of less than 2.3 dB from 20 to 85°C
