a Experiment setup for the fabricated chip. b Microphotograph of fabricated chip and c Scanning electron microscope photo for the nanophotonic media. d Confusion matrix on the test dataset after compensation. e Experimental normalized intensity distributions for all the samples in the test dataset after compensation. The ground truth labels for sample indices 0–9 are setosa, for 10–19 are versicolor, and for 20–29 are virginica. f Comparison of size and latency for on-chip inference systems4,5,7,11,12,13. Latency in this work is calculated in Supplementary Note 9. Lines indicate achievable latency ranges through component refinement. HandWritten-n represents the n-category handwritten digits dataset. *Area estimated from microscope images. †Latency obtained through theoretical calculations.
