Implication

Experimental study demonstrates ultrahigh refractive-index sensitivity in rectangular silica microfibers, highlighting potential applications for advanced biochemical detection.

Key Points

To develop and evaluate an ultrasensitive refractive-index sensor utilizing polarimetric interference within rectangular silica microfibers.
Fabricated an optical refractive-index sensor using polarimetric interference in a rectangular silica microfiber.
Measured sensor wavelength shifts across refractive-index variations around 1.33.
Analyzed the theoretical contributions of refractive-index-induced birefringence changes and dispersion properties to sensing sensitivity.
Achieved a measured sensitivity of 18,987 nm/RIU around a refractive index of 1.33, exceeding previously reported microfiber devices by one order of magnitude.
Demonstrated theoretically that ultrahigh sensitivity relies on both refractive-index-induced birefringence variation and unique rectangular microfiber dispersion properties.
Predicted that sensing sensitivity can be enhanced substantially when group birefringence approaches zero.
