Engineering and Regulatory Pathways for Designing Lenses and Light Pipes for PICs in Wearable Medical Devices

by Dr. Shourjya Sanyal, CEO, Think Biosolution

Optical elements such as light-pipes and lenses allow physical coupling of the PICs with the external environment. Optimal design is a critical part of the design for manufacturing (DFM) process and can deliver impact in terms of increasing both brightness of the source and signal to noise ratio of the optical sensor. One of the biggest challenges in photonic integrated circuits (PICs) is to design a system that continues interacting with the external environment without a loss of quality over time.

Engineering lenses and light pipes optimally can increase product lifetime for PICs. Since optical elements such as lenses and light pipes are often missing in the proof of concept functioning prototype stage, optimizing this design process can be a unique advantage for photonic OEMs specializing in last mile deliverables in the DFM step. In the case of PICs embedded within contact based wearable medical devices, correct design and regulatory process also minimize the risk of the product giving rise to skin rashes or blisters.

In this talk, we are first going to discuss various software tools for designing light pipes and lenses, various physical processes of the casting of light pipes and lenses, and how to build a quality control system for testing of light pipes and lenses. We are then going to talk about the various regulatory pathways and choice of materials in terms of designing light pipes and lenses for PICs in medical devices.

Interview

What drives you?
Helping make healthcare easy and accessible to all.

Why should the delegate attend your presentation?
To learn about design for manufacturing of biomedical PICs.

What emerging technologies/trends do you see as having the greatest potential in the short and long run?
On the short run, PICs will be used in specific use cases like high-speed communications across major nodes to medical devices used in hospitals. Once their usage is established, their market will scale to at-home products, such as routers and wearable medical devices to be used at home.

What kind of impact do you expect them to have?
PICs will have the effect consumer products same way PCBs accessibly revolutionized electronics a hundred years ago.

What are the barriers that might stand in the way?
I believe the biggest barrier for PICs is the design for accessible step.
