(Color) VA: variable attenuator; HW: half-wave-plate; M: mirror; L: lens; PP: penta prism; RR: retroreflector; PBS: polarizing beamsplitting cube; nPBS: nonpolarizing beamsplitting cube; PD: photodiode. (a) Schematic of the interferometer. The incoming pump beam (blue) is circularly polarized. The probe beam is linearly polarized and is split into two orthogonal polarization components by PBS1 along the local (dashed, magenta) and signal (solid, green) arms. Both PBS2 and PBS3 are used to filter unwanted polarization components. Lens pairs L1/L2 and L3/L4 are matched to form beam collimators. (b) Set point on the interference pattern. (c) The OB schematic shows that the linearly polarized probe beam is split into orthogonal components by the PBS and then detected.
(Color online) Demonstration of the expected linear relationship between the root signal power and the difference signal at the photodiodes. Each series was taken with a different power in the local arm. Additional data in the inset.
(Color online) Sample TRFR signals taken with the (a) MZI and the (b) OB. Each of the signals is fitted to a function of the form . (c) Scanning electron microscopy image of the sample window.
