Ramollari, H. (ECE) – An Optofluidic Spectrometer and Applications in Biosensing

Miniaturized spectrometers have the potential to replace bulky and expensive benchtop models. We have previously demonstrated a multimode interference (MMI) waveguide-based spectrometer that achieves high performance while minimizing its footprint.

In this talk, the integration of the MMI spectrometer into an optofluidic device is proposed. This integration opens up applications such as the detection of single particle fluorescence spectra and absorption spectra.

Moreover, adding a metasurface to the spectrometer waveguide is expected to enhance the sensitivity of single particle detection and simplify the analysis methods.

Finally, to improve the MMI waveguide spectrometer a new nanophotonic platform is proposed.
