Silicon photonics is just emerging as a genuine industrial technology driven by the insatiable needs for low-cost and high capacity data links in data centres. However, while the ability for silicon photonic chips to be manufactured at scale in CMOS foundries appears to be its greatest strength, in fact in comparison to electronics, photonic industrial applications are far too specialised to justify the almost unimaginable manufacturing throughput of CMOS infrastructure. As a result, many industries are re-evaluating their platforms and modes of manufacture – exploring lower volume advanced manufacture concepts and using materials that are not strictly CMOS compatible, such as specialised low-loss nitrides, and there is a return to the original workhorse of the integrated optics world from decades past: lithium niobate.
This talk will present a summary of the work being done by the Integrated Photonics and Applications Centre (InPAC) at RMIT University in the field of thin film lithium niobate. The talk will cover applications in high speed data communications, microwave photonics and sensors, such as optical gyroscopes. The talk will particularly focus on the potential for thin-film lithium niobate to offer ultraefficient nonlinear optical behaviour with the possibility to become a practical building block of industrially manufactured photonic chips.
