Pump lasers for Bismuth Doped Fiber Amplifiers (BDFA)

Pump lasers for BDFA in our product portfolio!

Exciting news from Innolume! The company launched the production of pump lasers for Bismuth Doped Fiber Amplifiers (BDFA) with an impressive power output of 500mW. These cutting-edge lasers operate at a wavelength of 1190 nm and are based on Innolume’s GaAs quantum dot technology, which offers exceptional reliability and power levels.

BDFA technology has been around since the 2000s, but it’s only recently become practical thanks to the availability of cost-efficient Bismuth doped fiber and high-power quantum dot pump lasers offered by Innolume. BDFAs have the potential to significantly extend the reach of O band transmission to 80km spans, which could replace C band fiber links with O band links. This is great news for companies looking to increase the bandwidth of their existing fiber links.

DFBs with optical isolators to enhance stable operation!

New DFB-VO in our product portfolio!

Innolume`s Distributed Feedback Lasers are now available with built-in optical isolators to enhance stable operation of laser.

This is an option for fiber coupled DFB modules in 1020-1330nm wavelength range.

Any wavelength is possible with just 1nm step tolerance. Our DFBs are suitable for seeding application and usage in DWDM systems.

Review the new specifications in DFB product section and contact us for the details!

Our partner Alfalume announces availability of 1.3 μm high power uncooled QD Lasers

Alfalume Inc. in partnership with Innolume GmbH, today announces sample availability of its O-band high power InAs/GaAs Quantum Dot DFB lasers which offers best-in-class output power, wall plug efficiency, temperature range as well as fundamentally better reliability of QD lasers compared to QW counterparts.

The Aflalume QD lasers provide significant benefits for high speed datacom transceivers, including record high power and conversion efficiency at temperatures above 85℃ without requiring thermoelectric coolers, optical isolator free operation, and lower cost due to significantly reduced component costs and better assembly yields.

“Our QD laser technology matches the operation temperature of photonics to the highest operating temperature of modern electronics. There is no other technology today which can provide the power level of O-band DFB lasers above 200mW with power efficiency of 20% at 105°C with the ability to operate efficiently up to 150°C” said Alexey Kovsh, Alfalume CEO. “Our uncooled lasers are ideal for pluggable transceivers offering the highest efficiency at high temperatures”.

QD DFB lasers offer the following performance characteristics: 

For 800G/1600G-DR8, a single QD laser can be used for all eight channels, resulting in lower component counts, better assembly yield and lower cost optical transceivers. QD Lasers are ideal for both Silicon Photonics and all new EO Modulation technologies including TFLN and BTO/Si. In addition QD Lasers are ideal for Remote Laser Modules for CPO and LIDAR applications. 

“The power of a single Innolume laser allows us to have a significant power margin for our DR8 Lithium Niobate modulators ‘, said Xinlun Cai, Liobate CEO.  “This enables better manufacturing yield and lower cost transceivers.”
