Moore’s law, which dictates the doubling of transistors on microchips every two years, has driven traditional computing technology for many years. The demand for higher speed, larger bandwidth, lower energy consumption, and improved security and stability in information technologies continues to grow. However, as we near the physical limits of miniaturisation, new approaches are needed to continue advancing computation. Integrated Photonic Chips (iPC) have emerged as a promising successor to silicon chips. With the continuous development, iPCs which offer the desired features including high speed and low power consumption, has become the best solution for high-throughput communication technology. However, as 3D photonic chips move towards commercialisation and industrialisation, existing fabrication capabilities face significant challenges concerning precision, reproducibility, and scalability to fulfil the needs for R&D and manufacturing. There is currently no effective measure to accurately characterise the three-dimensional structural changes formed inside an optical crystal by femtosecond laser, as well as the resulting refractive index distribution and morphology. To fabricate 3D optical structures in optical crystals, the difference in refractive index introduced by laser processing is particularly important, which determines the design of the component and its loss. Therefore, to effectively characterise the fabricated nanostructure/nanopatterns and provide timely feedback to the fabrication process has become one of the key challenges in quality control for processing 3D photonics chips. HoloView 3DRI, the 3D in-situ refractive index characterisation system designed by Innofocus, has proved to enable characterise the 3D spatial refractive index distribution with our newly-developed optical imaging technology and image reconstruction algorithm. The system can precisely measure the refractive index distribution in material and effectively reconstruct the refractive index distribution, and form image of the 3D structure with an accuracy of 10-4. It is non-destructive and non-invasive, and it allows real-time monitoring the fabrication process, making it valuable for the applications in the disciplines of all-optical communications, sensors, biophotonic and micro/nano optical and photonic devices. The key properties of an optical component are its refractive index distribution and surface morphology. High-performance optical components can only be fabricated when meeting requirements for both of the properties. Otherwise, distortion in electric field pattern, transmission loss and imperfection will occur, degrading the performance of the components. Meanwhile, by understanding the refractive index variation and distribution, properties of the optical material and components are quantified, which can be used to indicate whether the material or component is damaged. For those optical components that are sensitive to variation of refractive index, e.g. optical waveguide and optical fibre gratings, there is no standard quantitative method to characterise their 3D refractive index distribution. This issue has become a bottleneck for accurately designing and fabricating optical components like 3D photonic chips. To solve, Innofocus has developed world-unique technology of 3D spatial characterisation of refractive index to measure the refractive index difference between the structure designed and the substrate material, with an accuracy of 10-4. The system can not only precisely measure the distribution of refractive index differences, but also reconstruct the 3D surface morphology of the fabricated structure. The main functions of the Innofocus HoloView 3DRI include: In-situ inspection of the refractive index difference, along with the 3D spatial distribution of the refractive index and surface smoothness of femto-laser-processed optical components and structures. All of these can then contribute to optimising laser processing parameters. Quantitative measurement of both the surface and internal refractive index distributions of the components, followed by a comparison with the original design input. This helps to ensure whether the fabrication outcome is optimal in terms of the desired quality requirements (e.g. self-inspection for defects and alignment with the design), allowing on-site correction of fabrication conditions of the optical components. Imaging functionality which visualises the quantitative measurement of the refractive index distribution. HoloView 3DRI provides three-dimensional refractive index imaging display functionality which can visualise the observed refractive index distribution outcome. Based on the observed distribution, novel physical mechanisms of laser-material interactions can be discovered, displayed in a trustworthy and aesthetically pleasing manner through three-dimensional imaging.

Innofocus's NanoPrint 3D Intelligent Laser Nano-fabrication System. Innofocus Photonics has developed the world's first and only intelligent laser nanofabrication system with in-situ refractive index imaging characterization capability, which is a ground-breaking invention. Based on this patented invention, they have achieved the first in-situ characterization of three-dimensional refractive index difference distribution, which is a fundamental breakthrough in the field of laser processing. Innofocus's commercialized nanofabrication equipment based on multiple patented technologies is the world first system to ever achieve in-situ laser nanofabrication characterization of three-dimensional refractive index distribution, which is a fundamental breakthrough in the field of laser processing. Innofocus provides laser of multiple wavelength options including 450nm, 488nm, 532nm, 633nm etc., and can customize laser wavelength to be used according to customer requirement. Innofocus's nanofabrication system have unique technical advantages in terms of light field modulation. For example, our software system can generate phase maps for aberration correction in real time, based on the processing depth calculated after locating the material surface, and quickly update them on the spatial light modulator to achieve optimal compensation for each processing depth. Furthermore, since the laser focal spot runs along a specific designed trajectory in 3D space during the processing, it may move continuously at different depths. We designed AI-assisted software system to realize real-time compensation according to the depth where the focal spot is located during the continuous processing, to ensure quality and consistency. With the support of Innofocus's unique beam shaping function, we can adjust the beam focus and extend one of the focus dimensions (perpendicular to the fiber core direction) to inscribe in a pancake-shape focus. This method inscribes in a circular interface. Furthermore, this method can directly adjust the focus to match the specific parameters of the fiber core. The advantage of using this method is that it enables high-speed processing of FBGs with point-by-point writing. Innofocus's system has excellent performance in this area and completely automated the process for users, allowing automatic continuous image acquisition and computational reconstruction without multiple background acquisitions. The speed of the completed process depends on the configuration of the computer. A real-time reconstruction speed of 0.5 Hz can be achieved with the standard configuration of a small workstation. Speed can be increased with more advance-configured workstations. For example, Innofocus' standard SLM achieves a maximum power of 800 mW/cm2. Thus, depending on the SLM irradiated area, the maximum power is 1.06 W. If set higher customised SLMs, 2 W/cm2 can be achieved with a maximum power reaching 2.654 W. The surface tracing function of Innofocus's nanofabrication system is a valuable invention that ensures accurate processing position throughout the whole processing area, enabling large-area processing of micro and nano optical components. Innofocus's unique multi-focus parallel fabrication function, which divides the laser energy into hundreds or thousands of focal points for parallel processing, in accordance with the desired processing target, increases the productivity of 3D laser nanofabrication technology by hundreds or thousands of times and achieves a breakthrough in large-area processing from the principle.
