Mitsubishi Electric to Ship Samples of Wider-temperature-range CWDM 100Gbps (53Gbaud PAM4) EML Chip for Data Centers
Will reduce power consumption and costs of 400 Gbps optical transceivers for data centers
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.
