Mitsubishi Electric to Ship Samples of Wider-temperature-range CWDM 100Gbps (53Gbaud PAM4) EML Chip for Data Centers

Rhea-AI Summary

Mitsubishi Electric announced the shipment of samples for its new 100Gbps EML laser diode chip, set to begin on November 1. This chip will serve as a light source in 400Gbps optical transceivers for data centers, significantly reducing power consumption and costs. The chip's unique hybrid waveguide structure allows operation at temperatures from 5 to 85°C, eliminating the need for conventional temperature-control units. This innovation is expected to enhance efficiency in optical fiber communication systems.

Positive

• Introduction of a new 100Gbps EML laser diode chip expected to lower power consumption and costs.
• Wide operational temperature range (5 to 85°C) improves flexibility in data center applications.

Negative

• None.

Will reduce power consumption and costs of 400 Gbps optical transceivers for data centers

TOKYO--(BUSINESS WIRE)-- Mitsubishi Electric Corporation (TOKYO:6503) announced today that it will begin shipping samples of its 100Gbps (53Gbaud) four-level pulse-amplitude modulation (PAM4) electro-absorption modulator (EML) laser diode chip for coarse wavelength division multiplexing (CWDM) on November 1. The semiconductor diode is expected to be applied in sets of four EML chips as a light source in optical transceivers for 400Gbps optical fiber communication in data centers. Thanks to the new EML’s operability in a wider range of temperatures, it will help to lower the power consumption and costs of optical transceivers by eliminating the need for conventional temperature-control units.

1) High-speed, wider-temperature operation with unique hybrid waveguide structure

• Unique hybrid waveguide structure (Fig. 1) combines a buried heterostructure laser diode for high optical-output-power and a high-mesa waveguide electro absorption modulator (EAM) for a high extinction ratio and wide frequency range.
• 53Gbaud PAM4 operation is available in temperatures ranging from 5 to 85°C (Fig. 2) due to optimized design parameters for the laser diode and modulator sections.
