PICEO: A new manufacturing system for integrated optical components

Photonics is applied in numerous, diverse fields: medicine, life sciences, ICT, lighting, defence and security, among others. Currently, 60% of the costs of manufacturing photonic components are due to processes of encapsulating and embedding secondary optical elements in photonics integrated circuits (PIC), in which the LED is considered the simplest PIC.

The Centre for Sensors, Instruments and Systems Development (CD6 UPC) has developed a new manufacturing process for PICs, called PICEO, by which optical elements are integrated by injection of high-quality plastics (thermoplastics). This process cuts manufacturing costs and improves speed and performance compared to the current processes of PIC encapsulation in injection moulding. It redefines the current optical outlook in terms of component design and the manufacturing process.

The new PIC encapsulation process overcomes the limitations in current manufacturing processes: the production bottlenecks in terms of time, cost and energy consumption due to high plastic curing time (thermostable), which can be up to 4–5 hours. There are also restrictions in the positioning of optical elements when the PIC is assembled, and any variation can cause errors in the functioning of the final device. In addition, the components should be aligned in independent steps, which can lead to a lack of precision and deficient performance of the device. All the aforementioned factors lead to high associated manufacturing costs.

The PICEO manufacturing process based on thermoplastic moulding enables the incorporation (embedding) of secondary optical elements at the same time as encapsulation, which in turn leads to advances in the following aspects:

  • The technical characteristics of the components are improved: the volume is reduced and there are no limitations to the form of the injected optics. The use of free forms of optics improves performance and efficiency by up to 10% due to a reduction in the number of components required for the process. This new technology also enables the encapsulation to be customised for various applications, such as street and road lighting.
  • As positioning errors are reduced, the industrial manufacturing costs could be cut by up to 50%.
  • There are environmental benefits due to less energy consumption, which could be reduced by up to 50%. The efficiency of raw material use increases as a result of a lower rate of rejection of manufactured parts, as there is greater control of the manufacturing parameters (positioning).

This technology is expected to be launched on the market in 2020. Initially, it will be focused on key markets such as LED lighting, ICT, sensors and photovoltaic energy, which represent almost 70% of the market volume, at around 139 million euros. With this new low-cost process and high quality, PICEO will help Europe to compete on the global market, even with regions where the labour costs are lower. It will contribute significantly to maintaining the current two percent growth rate in the PIC industry.
