lithium niobate / 08 Industry / 8.6
8.6 Market size: ranges by evidence grade
L1 What the forecasts say
Market-research firms publish forecasts for thin-film LN modulators that differ by a factor of 6.5 in the base-year value and 12 in the forecast value E. None of the public teaser pages shows data or method. No single headline figure exists.

Spread E: TFLN modulators, base year US$73-476 M (2024/2025), forecast US$0.3-3.8 B (2030-2034); no public TFLN figure from LightCounting or Yole was found. Bulk LN crystal and wafer, about US$130-200 M (2024), GII outlier excluded; whether these include SAW-grade LT is not stated by any source.
Context
RF filter market (Yole): US$7.3 B (2021), US$8.2 B (2025) C (snippet only).
L3 Why there is no single number
- Definitions differ (chip vs module, bulk vs thin film, substrates in or out); base years differ; teaser pages are not reports.
- The strips plot each bar on a log axis from base to forecast; the axis spans US$10 M to US$10 B; the CAGR column is the publisher's, not recomputed. No sum, average, or consensus line is drawn, and no currency is converted.
- Unsourced numbers in Chinese finance articles (wafer price peak "CNY 28,000, about 7x", supply gap "about 40%", modulator share of module cost "10-15%") are LG and not plotted LG.
- Quality flags: the Intel Market Research player list names NeoPhotonics (acquired by Lumentum in 2022) and "II-VI Photonics Division"; 24marketreports lists AVANEX (defunct).
