Recently, I have been working on photonic sensors, and my latest project involves an innovative design for a cancer detection sensor using a photonic ring resonator structure in a label-free setup. In biosensors, three key parameters determine sensor quality: Sensitivity, Quality Factor (QF), and Figure of Merit (FOM). My unique optimization approach has resulted in approximate values as follows:

• Sensitivity (S): ~42-48 nm/RIU
• Quality Factor (QF): ~480,000
• Figure of Merit (FOM): ~13,000

Additionally, the structure achieves an impressive FWHM of 0.003 nm. For comparison, ideal ranges for these parameters typically are:

• Sensitivity: 50–300 nm/RIU (ideal: 200–500 nm/RIU)
• QF: 10,000–100,000 (ideal: >100,000)
• FWHM: 0.01–0.1 nm (ideal: 1000 RIU⁻¹ for high-precision sensors).

As the saying goes, “every achievement has its cost,” and there are always trade-offs in design. The high QF and FOM in my design highlight exceptional sensor performance, although the Sensitivity remains within an average range. Given these results, I am interested in feedback from the community—do you think these results are promising enough to submit for publication in journals focused on photonic sensors?

Please find attached the formulas for these parameters.

Your insights and suggestions would be greatly appreciated!
