PIC Magazine, October 2023
The rapid growth of photonic integrated circuits is driving the need for fast innovation, and this is made possible by the development of Photonic Wire Bonding (PWB), which creates low-loss, 3D free-form connections between optical components. Just as electrical integrated circuits have benefitted from electronic wire bonding, photonics innovations will now advance on a faster trajectory with PWB.
Built on advanced 3D nano-printing technology, PWB is inherently a fully automated process and provides a high degree of design flexibility.
Additionally, 3D nano-printing has been used for several years to fabricate facet-attached micro-optical elements on optical chips and fibres, enabling low-loss coupling with relaxed alignment tolerances and wafer-level probing of optical devices. With both PWB and facet-attached micro-optical elements in their technology portfolio, Vanguard Automation’s mission is to advance photonic packaging and assembly by providing scalable 3D nano-fabrication solutions, allowing seamless transitions from prototyping to industrial high-volume production.
