IQE`s III-V MBE Technology To Advance Silicon Photonics

Along with UCSB, IQE has grown 1.3μm InAs quantum dot lasers on silicon
                                                                                                                                               

IQE has announced that its epitaxial wafer technology has been used to help develop next generation quantum dot lasers on silicon substrates.

This is aimed at enabling the integration of photonics devices with silicon technology for low cost, high volume data communication applications.

The results of work by IQE in conjunction with the University of California Santa Barbara (UCSB) will be presented at the Optical Fibre Communications Conference (OFC) which is taking place this week in San Francisco.

Silicon photonics, which combines compound semiconductor devices with low cost silicon substrates, offers the potential to integrate highly sophisticated laser devices with more traditional low cost CMOS driver and waveguide technology.

The researchers believe this work represents an important step towards large-scale photonic integration in an ultra low-cost platform for high volume consumer applications which will lead to the mass adoption of silicon photonics.

A key feature in enabling the cost effective integration of photonic devices with silicon technology is the ability to grow compound semiconductor quantum dots onto silicon substrates using MBE growth technology that has a proven track record for high volume manufacturing of wireless products.

Researchers at UCSB demonstrated a novel quantum dot laser design that not only is grown on silicon but that performs as well as similar lasers grown on their native substrates.

IQE provided both the engineered germanium/silicon substrates and the III-V MBE template growth. The growth of the quantum dot laser structure and fabrication of the laser components were performed at UCSB.

The UCSB team will discuss its results at the OFC Conference and Exposition, being held March 9th to 13th in San Francisco.

The presentation W4C.5. titled, “High Performance 1.3μm InAs Quantum Dot Lasers Epitaxially Grown on Silicon," will take place on Wednesday, March 12th at 5:00 p.m. in room 121 of the Moscone Centre.

 



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.
