Summary

We developed a compact optical spectrometer using guided-mode resonances (GMR) for spectral encoding. This technology enables precise chemical sensing and bacterial identification for applications like smartphone spectroscopy.

Area of Science:

Photonics and Optical Engineering
Nanotechnology
Spectroscopy

Background:

Miniaturizing optical spectrometers is limited by the spectral resolution and optical path length trade-off.
Existing technologies face challenges in achieving high resolution in compact form factors.

Purpose of the Study:

To present an ultra-compact spectrometer architecture using angular dispersion of guided-mode resonances (GMR).
To demonstrate a deterministic spectral encoding method for enhanced sensing capabilities.

Main Methods:

Utilized angular dispersion of guided-mode resonances (GMR) for spectral encoding.
Designed a symmetric multi-layer architecture with a low-index metasurface-grating and high-index guiding layers.
Exploited phase-matching at oblique incidence for linear tuning of resonant wavelength.
