Launched by iBULe Photonics at Oi26
iBULe Photonics has launched the world’s first submarine hydrophone sensor using third-generation piezoelectric single crystal technology at Oceanology International 2026 (Oi26)
The new acoustic sensor is a major advancement in underwater detection capability. By harnessing the properties of third-generation single-crystal materials, the hydrophone provides 9dB greater sensitivity than ceramic PZT hydrophones. This enhancement enables longer detection ranges and clearer signal processing, including in complex, noisy undersea environments.
Developed for next-generation naval sensing systems and advanced ocean-monitoring applications, the technology can enhance situational awareness and improve acoustic detection of submarines and underwater platforms.
During Oi26, iBULe Photonics also outlined its ambition to expand into the North American defence market, leveraging the role of high-performance acoustic sensing technologies in enhancing detection capabilities for future submarine fleets. Among the company’s potential collaborations are opportunities linked to the Canadian Patrol Submarine Project, a major procurement programme which will replace the Royal Canadian Navy’s Victoria-class submarines with a new fleet of modern long-range patrol submarines.
Those who visited the iBULe Photonics stand at Oi26 were also introduced to a visual presentation that emphasised the company’s technological development and its long-term vision for delivering advanced sensing solutions.
Dr Sang-Goo Lee, CEO of iBULe Photonics, said, “Our third-generation single crystal technology represents far more than an incremental improvement – it marks a fundamental step forward in underwater acoustics. With a 9 dB sensitivity advantage over traditional PZT sensors, we are providing the ‘eyes and ears’ required for the next generation of naval sensing systems, as well as other maritime and ocean science applications. We are excited about the opportunities to support major global programmes such as Canada’s CPSP.”
