High-performance lasers for data center and telecom applications
Lumentum manufactures indium phosphide (InP) externally-modulated lasers (EMLs) in our internal wafer foundry. These EMLs consist of a distributed feedback (DFB) diode lasers followed by a monolithically integrated electro-absorption modulator (EAM). With a DFB, a distributed Bragg reflector is used to accurately lock to the desired wavelength. The DFB runs in a continuous wave (CW) mode. The DFB output is adjusted to achieve the appropriate output power. Then, the EAM is used to modulate the light for either the NRZ or PAM4 output as needed. Lumentum offers 25G NRZ LAN-WDM and 100G PAM4 CWDM high-performance lasers for use in data center and telecom applications.

EML 25G NRZ 100G PAM4 LAN-WDM
|
The HL13B2CP00-Ln (Ln: L0, L1, L2 or L3) is a cooled externally modulated laser (EML) diode chip for 25 Gbps NRZ or 50 Gbps PAM4 operation. The setting temperature of the chip (TLD) is as high as 52.5°C for the purpose of low power consumption of the optical transceiver. LAN-WDM 4 wavelengths of 1295.6/1300.1/1304.6/1309.1 nm are available. Offered as bare die, it is designed for use in the dry N2 hermetic sealed package.

EML 100G PAM4 CWDM
|
The HL13B5CP00-Ln (Ln: L0, L1, L2 or L3) is an externally modulated laser (EML) diode chip (bare die) for 25G or 50G baud PAM4 operation. IEEE based CWDM4 wavelengths of 1271/1291/1311/1331 nm are available. The performance-based operating temperature range is from 20°C to 70°C for the purpose of uncooled operation of the optical transceiver.
