Abstract
An in-line all-fiber etalon, formed by a self-enclosed
Fabry–Perot cavity inside an optical fiber fabricated by using
157-nm laser micromachining, is first demonstrated in this paper. This
etalon has almost perfect sensor characteristics, such as excellent
interferometric fringe contrast of up to ${\sim}30$ dB, low thermal cross-sensitivity, great potential to realize
mass-production with good reproducibility, low cost, super capability to
operate in harsh environments, etc. The static, quasi-static, and dynamic
strain characteristics of the etalon sensor are investigated, which prove
that such an etalon could meet versatile applications for strain
measurement.
