Comments about birefringence dispersion, with group and phase birefringence measurements in polarization-maintaining fibers

Journal of the European Optical Society-Rapid Publications, 2023
A recent JEOS-RP publication proposed Comments about Dispersion of Light Waves, and we present here complementary comments for birefringence dispersion in polarization-maintaining (PM) fibers, and for its measurement techniques based on channeled ...

Development of a Mercury Bromide Birefringence Measurement System Based on Brewster’s Angle

Sensors, 2023
Mercury bromide (Hg2Br2) has been used to develop acousto-optic tunable filters (AOTFs) because it has several advantages, including a high refractive index, a broad optical bandwidth, and a relatively high figure of merit.

Distributed Birefringence Measurement of a Polarization-Maintaining Fiber With an Extended Range Based on an Enhanced Brillouin Dynamic Grating

IEEE Photonics Journal, 2020
A distributed birefringence measurement of a polarization-maintaining fiber (PMF) can be realized by using a Brillouin dynamic grating (BDG). However, the pump depletion decreases the intensity of the BDG along the PMF and limits the measurement range to

Measurement of the magnetic birefringence of noble gases [PDF]

Journal of the Optical Society of America B, 1984
The Cotton–Mouton constants of argon, krypton, and xenon have been measured relative to nitrogen at room temperature and ambient pressure for λ = 514.5 nm. Upper limits for helium and neon have been determined. The sensitivity of the apparatus was Δnmin = 0.8 × 10−14 for a measuring time of 1 sec.
