The optofluidic system and the MZI configuration - Microfluidic droplets characterisation

Microfluidics can generate droplets to apply to a broad range of laboratory applications. However, the current imaging techniques used for droplet characterization are time-consuming and need large data storage. This project developed a new opto-microfluidic system for reliable and reproducible droplet labelling using optical waveguides in a Mach Zehnder’s configuration.
The microfluidic system is composed of a cross-junction droplet generator connected to a straight channel. The MZI splits the light into two arms reaching two different parts of the channel.The photodiode collects the light exiting the waveguide and the signal is transduced to a data acquisition system (DAQ).
