Fig. 5: Performance comparison with state-of-the-art competitors.
From: Integrated reconstructive spectrometer with programmable photonic circuits
Comparison with various reported spectrometers regarding (a) the resolution and bandwidth, (b) the spectral pixel-to-footprint ratio and the spectral pixel-to-spatial detection channel ratio, respectively. The solid red star in (a) and (b) represents the experimental performance of our device. The dashed gray star in (a) denotes the simulation performance when applying a larger number of sampling channels and curved directional couplers, while the dashed lines display the bandwidth-to-resolution ratios at different orders of magnitude. The dashed gray star in (b) represents the expected performance when applying the same spectrometer design to a standard 220 nm Si platform.
