Imec demos ultrasound sensor in silicon photonics

Imec, a leading research and innovation hub in Belgium, has demonstrated an optomechanical ultrasound sensor on a silicon photonic chip that has an unprecedented sensitivity due to an innovative optomechanical waveguide.

By leveraging this high-sensitivity waveguide, Imec's 20-µm small sensor has a detection limit two orders of magnitudes better than piezoelectric elements of identical size. 

Potential clinical and biomedical applications of ultrasonic and photoacoustic imaging include deep-tissue mammography and the study of vascularization or innervation of potential tumorous tissue. 

 “The sensor we have demonstrated will be a gamechanger for deep tissue imaging in otherwise non-transparent tissues such as skin or brain. For applications such as sub-cutaneous melanoma imaging or mammography, it enables a more detailed view of the tumor and vascularization around, aiding in a more detailed diagnosis,” says Xavier Rottenberg, fellow wave-based sensors and actuators at imec.

Imec said its solution is based on a highly sensitive split-rib optomechanical waveguide fabricated using new CMOS-compatible processing. The sensitivity is two orders of magnitude larger than a state-of-the-art device. A low detection limit can improve the trade-off between imaging resolution and depth for ultrasound applications, and is crucial for photoacoustic imaging, where pressures are up to three orders of magnitude lower than in conventional ultrasound imaging techniques. 

Finally, a fine-pitched (30 µm) matrix of these tiny (20 µm) sensors can be easily integrated on-chip with photonic multiplexers. This opens the possibility of new applications such as miniaturized catheters because the sensor matrices require only few optical fibers to be connected instead of one electrical connection per element in the case of piezoelectric sensors.

Belgium's Proximus deploys ADVA synchronization for 5G

Proximus is leveraging ADVA's Oscilloquartz timing technology to synchronize Belgium’s largest open mobile network. The deployment enables Proximus to improve speed, coverage and reliability for millions of mobile users throughout Belgium, while also preparing its network for next-generation services. The deployment includes ADVA’s core grandmaster devices, access boundary clocks and its enhanced primary reference time clock (ePRTC) solution,. ADVA’s partner is Arcadiz Telecom, a leading provider of connectivity solutions across the Benelux region.

Proximus’s new nationwide synchronization network is built on the OSA 5440, an ultra-stable timing solution optimized for deployment in core networks and the OSA 5412 family of cost-effective, mid-scale synchronization devices engineered for deployment in a wide range of locations. It’s anchored by the robust and proven OSA 3230B ePRC cesium clock installed in two central sites. This supports high levels of frequency stability compliant with the strictest ITU-T standards and, combined with the OSA 5440, ensures long-term stability of UTC time. The extended stability performance of ADVA’s ePRC provides immunity against GNSS outages – a crucial requirement for mission-critical applications that should not rely on satellite-based timing alone.

“For major mobile network operators like Proximus, our PTP grandmaster and boundary clocks and our ePRTC solution are the perfect tools. They enhance overall performance and deliver the precision timing necessary for 5G use cases. Our technology also enables other services such as broadcast networks to migrate to IP-based timing,” commented Jörg Urban, senior director, business development, Oscilloquartz, ADVA. “The OSA 5412 Series and OSA 5440 support a smooth and cost-effective migration to next-generation phase and frequency synchronization. And with our ePRTC solution providing robust backup for GNSS, Proximus’ mobile customers can be sure of high-quality, uninterrupted services with no loss of performance.”

Belgium's KU Leuven selects ADVA's FSP 3000 CloudConnect

The Katholieke Universiteit Leuven (KU Leuven), a leading research university in Flanders, Belgium, has deployed ADVA's FSP 3000 CloudConnect to enable 32Gbit/s Fibre Channel and 100Gbit/s Ethernet services.

KU Leuven's research and education (R&E) network is the first in the region to support Gen 6 Fibre Channel technology.

The deployment uses ADVA's FSP 3000 CloudConnect platform along with its QuadFlex line card and OpenFabric cross-connect – two technologies optimized for maximum flexibility and efficiency in metro data center interconnect networks.

ADVA’s Elite partner Arcadiz Telecom, which played a key role in the rigorous planning and smooth installation of the transport system, will also provide ongoing maintenance support.

“Through our close partnership with Arcadiz Telecom, we’ve been able to work with KU Leuven to push the boundaries of possibility for R&E networks. We’ve created a transport system capable of carrying much higher data volumes than has ever been achieved in this area before. It’s also a future-proof investment ready to scale even further in years to come,” commented Yann Evain, sales director, Benelux, ADVA. “One of the advantages of this network is that it enables KU Leuven’s data centers to maximize the performance of flash-optimized storage arrays. Having rapid access to phenomenal amounts of data frees academics to achieve even more. The new solution also delivers huge energy savings and, with its incredibly small footprint, occupies very little rack space. Its inherent scalability protects KU Leuven’s investments, helping the university maintain its reputation as a global technology leader and its top position in Reuters’ rankings of Europe’s most innovative universities.”
