Company profile
Poro Technologies Ltd is a Cambridge-based microLED pioneer and global gallium nitride material-technology developer advancing ultra-low-power, full-colour microLEDs on silicon for next-generation AR devices, optical interconnect, and photonic compute. The company is a University of Cambridge spin-out co-founded in 2018 by a University of Cambridge research team after a decade of research and development in GaN-related materials and device applications. Porotech officially moved out of the university after its first equity investment in January 2020. Its proprietary PoroGaN® material platform introduces controlled nanopores into GaN to tune electrical, optical, mechanical, and thermal properties, with the stated result of brighter and more efficient emitters together with robust manufacturability. Research into engineered porosity in GaN led Porotech to identify PoroGaN® as a platform applicable to multiple semiconductor-based applications. Using PoroGaN®, Porotech developed DynamicPixelTuning® Technology (DPT®), which enables a single microLED chip to produce any visible colour from one pixel, including white light. The company describes DynamicPixelTuning® as the first microLED architecture in which each pixel can emit the full colour gamut, simplifying optics, reducing form factor, and enabling daylight-readable, energy-efficient microdisplays. Porotech operates an end-to-end design, manufacture, and test loop covering epitaxy and device design, wafer processing, heterogeneous integration with CMOS, advanced packaging, and in-line metrology, supported by pilot-plant and mass-production lines. Its senior management teams collectively have more than 15 years of semiconductor and optoelectronics experience, and the company states that its growing team comprises more than 50 employees across Cambridge Headquarters in the UK, Hsinchu in Taiwan, and Arizona in the USA. In February 2023, Porotech marked the opening of a new Cambridge Headquarters with a new laboratory and clean room and held an open day at its Taiwan site with technology demonstrations. The company reports an expanding IP portfolio and partnerships across the UK, Europe, North America, and Asia, while providing mass production and volume integration to OEMs. Porotech has received recognition including the I-Zone 'Best Prototype' Award at Display Week 2022, the IOP 'Business Start-Up' Award, SID's People's Choice Award for 'Best New Display Component', and an International Business Awards Gold Stevie for 'Emerging Technology'. Its stated mission is scalable, sustainable photonics that reduce system power and cost while enabling new human-machine interfaces in wearables, industrial, healthcare, and compute applications. Porotech says its technology is customizable and adaptable and sets an aim to have the technology in all displays by 2030 while continuing development work with customers.
Exhibits
Porotech's supplied display technology includes The Perfect Red MicroLED, and the company states that its MicroLED technology changes how displays are manufactured. Its PoroGaN® material platform uses controlled nanopores in GaN to tune electrical, optical, mechanical, and thermal behavior for emitter performance and manufacturability. DynamicPixelTuning® (DPT®) uses proprietary PoroGaN® so that a single microLED chip can produce any visible colour, including white light, from a single pixel. In the architecture described by Porotech, each pixel can emit the full colour gamut, which simplifies optical systems, reduces form factor, and enables daylight-readable, energy-efficient microdisplays. The company's silicon microLED work is directed at next-generation AR devices, optical interconnect, and photonic compute. Its end-to-end manufacturing scope runs from epitaxy and device design through wafer processing, heterogeneous CMOS integration, advanced packaging, and in-line metrology, with pilot and mass-production lines supporting the flow. Porotech identifies collaboration areas in integrated-photonics fabrication using Si, SiN, and InP, as well as metasurfaces, holographic systems, drivers and control electronics, and quantum control. The company also lists connectivity, AI, and quantum testbeds; collaboration on advanced packaging and high-throughput metrology; and consortium partnerships around low-power emitters and pixel architectures. The end-user areas named for these technologies include AR, optical communications, and quantum or photonic compute, while the broader mission also reaches wearables, industrial, healthcare, and compute interfaces. Porotech presents itself as providing microLEDs for everyone, everywhere and as a microLED pioneer and global GaN material-technology developer, linking the displayed microLED products to its underlying materials platform.
