Furukawa Electric Develops Electro-Absorption Modulated Laser with Integrated Semiconductor Optical Amplifier

Realizes both low power consumption and high optical output power of 50 Gbaud, double the current output

OFC 2023, Booth 3229, San Diego, California, March 2, 2023 - Furukawa Electric Co., Ltd. (FEC) announces the development of a high optical output power 50 Gbaud electro-absorption modulated laser (EML) “FOL13EBxCS” with integrated semiconductor optical amplifier (SOA).  By integrating a SOA into the EML, this new product realizes approximately double the optical output power at the same power consumption level compared to existing EML.  Realizing both high optical output power and low power consumption, contributes to the establishment of optical communication networks that support the commercialization of 5G.

  • Background

The installation of 5G networks for mobile phones has resulted in more cloud services that operate at faster speeds and larger data volumes, and following increased data traffic at the network edge, the demand for signal light sources for short and medium-range distances is increasing. EML has excellent signal waveform and high-speed operating characteristics, and it is broadly used as a laser source for medium-range distances (10km) at speeds of 100Gbps and higher. In addition to addressing longer network distances and larger data volumes, along with the growing needs for higher optical output power, it is also necessary to limit power consumption.

  • Details

By integrating a SOA into the EML, this new product realizes approximately double the optical output power at the same power consumption level compared to existing EML. With the existing EML, optical output power is increased by increasing current flow to the laser, and as a result, power consumption increases in proportion to the increase in optical output power. By integrating a SOA that can increase optical output with high efficiency, the newly developed EML realizes both higher optical output power and low power consumption.

When using this product as part of a 100G-400G Ethernet and next-generation high speed PON system, it should be possible to extend the distance of metro access networks.

In addition to laser sources for long haul and metro networks (for medium and long distances), Furukawa offers a lineup of laser sources for a broad range of optical networks, including data center and access networks (for short and medium distances, including this product).
