High-stability transfer of an optical frequency over long fiber-optic links

PA Williams, WC Swann, NR Newbury - JOSA B, 2008 - opg.optica.org
We present theoretical predictions and experimental measurements for the achievable phase
noise, timing jitter, and frequency stability in the coherent transport of an optical frequency …

Coherent transfer of an optical carrier over 251 km

NR Newbury, PA Williams, WC Swann - Optics Letters, 2007 - opg.optica.org
We transfer an optical frequency over 251 km of optical fiber with a residual instability of 6×10^−19
at 100 s. This instability and the associated timing jitter are limited fundamentally by …

Optical, thermo-optic, electro-optic, and photoelastic properties of bismuth germanate (Bi4Ge3O12)

PA Williams, AH Rose, KS Lee, DC Conrad, GW Day… - Applied Optics, 1996 - opg.optica.org
To assess the suitability of bismuth germanate as an electro-optic material for high precision
applications, we have confirmed and extended previous data on its refractive index, electro-…

Rotating-polarizer polarimeter for accurate retardance measurement

PA Williams, AH Rose, CM Wang - Applied optics, 1997 - opg.optica.org
We demonstrate an automated polarimeter based on a rotating polarizer for the measurement
of linear retardance independent of laser power and detector gain. The retardance is …
