iSLight offers photonic solutions powered by SLEDs for machine vision instruments, VR/AR headsets, projection displays, medical devices, lighting systems and ranging systems(LIDAR and 3D sensing). Unlike LEDs, Lasers or SLEDs in the market iSLight provide speckle free, high and customized power, low production cost, efficient, and compact light emitters.
- A speckle-free source increasing the definition and quality of projected light images
- Currently blue (400-450nm) but also can scale to other wavelengths (green, red, infrared)
- High efficiency (laser quality without the speckle)
- High light directionality (Low entendu) which enables efficient light coupling to target
- Wafer-scale packaging and testing devices which reduce production cost·
- Scaling in power by going to arrays
- Scaling in volume by using 100mm diameter GaN wafers
- Ultrashort pulse
- Currently in development phase so opportunity to influence the design of iSLight SLED modules
- Flexible light modules for multiple applications
In a laser diode, the optical waveguide and reflective facets create an optical cavity (resonator) and facilitate the emission of amplified stimulated by overcoming optical losses. The emission spectrum is formed by narrow or multiple narrow bands depending on the laser characteristics.
On the other hand, LEDs devices emit a broadband spontaneous light in all directions and have no amplified gain since the light is not confined in an optical cavity.
SLEDs exploit the process of amplified spontaneous emission (ASE) where the light of spontaneous emission is amplified only in a single pass through an optical waveguide as compared to amplification over multiple roundtrips in an LD. Furthermore, any kind of feedback in the optical cavity is avoided in a SLED, resulting in a broadband spectrum with no amplitude modulation (spectral ripple). Contrary to laser diodes, SLEDs gain increases with the current even much above the transparency conditions.

Who we are
Mr Brian Corbett: Brian Corbett received B.A.Mod degrees in Experimental Physics and Mathematics from Trinity College Dublin, Master of Science from Trinity College Dublin, and M. Eng. Sc. from University College Cork. He is leading the III-V materials and devices group at Tyndall and is the coordinator of ALIGHT which is a collaboration between European partners on semi-polar GaN and of COMPASS, a Marie Curie industry-academia partnership project with Seagate. His research area is the physics and technology of III-V based light emitting semiconductors with special emphasis on the use of advanced structuring technologies to permit integration and add additional functionality to devices enabling new applications. His research achievements include the invention of a low-cost method to obtain single frequency semiconductor lasers which is applicable across wavelengths and materials. The patent has been licensed by Eblana Photonics and is a core offering. He co-invented a method to significantly enhance the directionality of light from LEDs which has been licensed to Infiniled, a start-up company from Tyndall. He received a Researcher of the year award for his work with Intel.
Dr Juan Morales: Juan Morales obtained his doctorate studies from the Cork Institute of Technology in 2019. His research doctorate regarded the study of III-V novel semiconductor nanostructure, organic materials and minerals using advanced optical characterization. During his post-graduate, he was awarded a chair position and invited talks on the competitive international conference – SPIE photonic west conference. In 2019, he joined the high regarded III-V materials and devices group at Tyndall to work towards the commercialization and development of high power super-luminescent emitting diodes.
Mr. Gerry O’Carroll: Gerry is a graduate of the University of Limerick in Electronic Engineering and has held a number of senior technical and commercial positions in the semiconductor, industrial and communications industries over the past 35 years. He brings a wealth of experience having worked as a senior electronic design engineer, product marketing manager and sales and business development manager within Tier-1 companies including Analog Devices, Intel, Nortel Networks and Tellabs.
