Abstract

The performance of high-speed EML on sub-mount is discussed targeting 112 GBaud PAM4 modulations. The proposed sub-mount with high-speed EML demonstrates a high bandwidth of 80.4 GHz and a TDECQ value of 1.6 dB at 55 °C. The low TDECQ value of lower than 1.9 dB in a wide temperature range (20 °C - 70 °C) indicates that the proposed configuration is a promising candidate for 200G per lambda data center applications.
