Key Points

To design and demonstrate a high-resolution, compact spectrometer using a two-dimensional array of high-quality-factor photonic crystal nanocavities integrated with a planar waveguide.
Fabricated a compact two-dimensional array of high-quality-factor photonic crystal nanocavities coupled along a planar waveguide.
Evaluated device spectral resolution at an operating wavelength of 840 nm and assessed architectural compatibility with commercial optical detector arrays.
Achieved a narrow spectral resolution of 0.3 nm at an operating wavelength of 840 nm, matching the intrinsic bandwidth of the cavity mode.
Demonstrated architectural scalability adaptable to the visible and deep-infrared spectral regimes.
