RAAK-MKB proposal AutoCUE
When passive photonic sensor chips are used in lab-on-a-chip application, e.g. for blood analysis, an important aspect is the coupling of the active components (light source and photodiodes) to the chip. Several methods have been proposed to solve this, and in this project a solution using end-butt coupling will be developed. In end-butt coupling the light enters at one of the end faces directly into the waveguides (which run parallel to the chip surface). Good coupling to the waveguides on the chip requires fast, micrometer accurate alignment, which should be done autonomously when the instrument is going to be used in a medical practice. The proposed design consists of a two-step process. First, the chip, which is packaged in a cartridge, will be aligned as accurately as possible by a mechanical system of stops and guidance. This is the passive part. Next, by switching on the light source and scanning the optical fiber connected to it over a certain area, the position with maximum coupling can be found. The project should result in a demonstrator setup showing the feasibility of this solution.
Effectively, the project started just after the summer of 2020 and is currently showing first results. First, accurate measurements have been carried out, where the coupling was measured as a function of a linear or angular displacement between the fiber and the waveguide. Based on these measurements, the required accuracies for the six degrees of freedom could be determined. Next, a first proposal for the design of the cartridge and acceptor slot have been made. This design should guarantee maximum accuracy for the passive alignment step and is currently being realized and tested. Finally, a first procedure and algorithm for the active alignment process have been developed, which seem to be working nicely.
This project, funded under the SiA RAAK-MKB program is carried out by the following partners: Saxion University of Applied Sciences, University of Twente, Qurin Diagnostics BV, Delta Diagnostics BV, Beta Applied Research BV, LioniX International BV, PhiX BV, Huygens Engineers BV, SurfiX BV, Salland Engineering BV, IMS BV and with support from PhotonicsNL.
