Abstract

The proliferation of Internet-of-Things has promoted a wide variety of emerging applications that require compact, lightweight, and low-cost optical spectrometers. While substantial progresses have been made in the miniaturization of spectrometers, most of them are with a major focus on the technical side but tend to feature a lower technology readiness level for manufacturability. More importantly, in spite of the advancement in miniaturized spectrometers, their performance and the metrics of real-life applications have seldomly been connected but are highly important. This review paper shows the market trend for chip-scale spectrometers and analyzes the key metrics that are required to adopt miniaturized spectrometers in real-life applications. Recent progress addressing the challenges of miniaturization of spectrometers is summarized, paying a special attention to the CMOS-compatible fabrication platform that shows a clear pathway to massive production. Insights for ways forward are also presented.

  • Silicon photonic spectrometers for biosensing applications often require an operational wavelength incompatible with the C/L/O bands.

    “Silicon photonic spectrometers for biosensing applications often require an operational wavelength incompatible with the C/L/O bands154.”

    From Roadmapping the next generation of silicon photonics (2024) · cites this paper as [154]

    The Biomedical sensing section (page unavailable) identifies a 700–1100 nm sensing window for glucose and wavelengths of 730 and 850 nm for hemoglobin, supporting the point that some biosensing targets lie outside the named bands. It also describes a 1300–2500 nm glucose-sensing window; it does not establish that silicon photonic biosensing spectrometers often require wavelengths incompatible with all three bands.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
