Kyma's GaN Materials Help NRL To Advance Novel Optics

The supplier of crystalline aluminium nitride and gallium nitride materials has helped NRL to develop a new technology for commercial and defence applications
Kyma Technologies has helped Naval Research Laboratory (NRL) scientists to demonstrate a novel approach to making mid-infrared non-linear optics.


The products in question are important for a number of commercial and defence applications.


The market for nitride semiconductor devices was approximately $9 billion in 2011, and is expected to surpass $60 billion over the long term, including $30 billion in visible lighting applications and $30 billion in power electronics applications.


Today’s most prevalent approaches to non-linear mid-IR optical materials are based on periodically poled lithium niobate and related materials. They suffer from a dramatic drop-off in performance in the wavelength region beyond 4µm.


Addressing this issue, NRL has developed a dramatically different approach to conventional methods. They alternate the actual crystal orientation of the semiconducting nonlinear material to create promising structures from GaN grown by hydride vapour phase epitaxy (HVPE).


Kyma’s HVPE GaN has very low impurity levels and low defect densities which supports a large transparency window all the way out to 7µm. They also have a high thermal conductivity (over 250 W/m-K), and a high second-order nonlinear susceptibility, all important for non-linear optics applications.




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.
