II-VI Unveils 1W 980nm Pump Module

High-Power module provides EDFA designers with new options to increase output power per stage

II-VI Incorporated has launched a high-power, 1 watt, 980nm pump laser module, based on high-reliability laser diode technology from its in-house wafer fab in its Laser Enterprise Division in Zurich, Switzerland.

"This advancement in pump laser technology delivers the most efficient commercially available 980 nm pump laser in the world, both in terms of laser conversion efficiency and total module power consumption. It provides EDFA designers with new options to increase output power per stage within high-power DWDM solutions, while being more efficient and reducing overall cost of network ownership," said Simon Loten, GM of the II-VI Pump Laser Division. 

"The new module can also be used to replace pairs of lower power modules, enabling cost-effective, more thermally efficient and environmentally conscious designs. When compared with 14xx nm and competing 980nm solutions, the II-VI pump laser modules achieve very high power at significantly lower drive current and thermo-electric cooler power."

According to the company, the new 1W pump laser module enables up to 1050mW of kink-free optical power through a grating- stabilised single-mode fibre for easier integration into the EDFA system. The module is housed in the established 10-pin, mBTF (mini-Butterfly) format package which is quickly becoming adopted as the new market standard, providing an electrically and mechanically compatible pinout to legacy 14-pin packages, in a 75 percent smaller package. 

The product is fully qualified to the requirements of Telcordia GR-468-CORE and is RoHS 6/6 compliant. The 1W module is sampling to customers now, and will be ramping through the third quarter of 2015.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
