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.”

Innolume’s Quantum Dot technology for datacom market.

Over the whole its history Innolume was continuously working on bringing of Quantum Dots technology advantages to datacom (fiber optic communication) market. Well known high reliability, low sensitivity to optical feedback and operation at high temperature were always attracting a lot of attention from industry. “Thanks to all Tier 1 companies who have been supporting us on our development way, such progress with releasing of the products that close to market demanding targets would not be possible without their close cooperation” saying Alexey Shkolnik, Director Bus.Dev. of Innolume.

At this moment “Innolume for Datacom” portfolio features a variety of product lines designed to serve many different datacom architectures approaches:

Temperature insensitive up to 100°C DFB Laser with 100mW output power is introduced.

100mW DFB Laser at 100°C

Innolume has developed and released first generation of temperature insensitive up to 100°C DFB Laser with 100mW output power and ~20% wall plug efficiency which can become an enabling component for the future datacom equipment.

This product should substantially reduce laser costs and power consumption in datacom market. We estimate 90% cost savings for laser (by eliminating multiple, low output power lasers) and up to 50% total power savings due to uncooled operation saving energy and environment one laser at a time. By enabling lower channel costs, it will accelerate the ability of datacentres to handle burgeoning demand in data processing. Featuring 180mW@100°C and providing 100mW at the fixed current in the whole 25-100°C temperature range this high-power DFB laser is targeting both to substitute existing solutions as well as to create a new market segment as it is enabling a completely new system architecture.
