The paper describes the experimental stand and the results of studies of aberrations of the sources of a reference spherical wave (SRSW) based on a single-mode optical fiber with a sub-wave output aperture using the optical part of the recording system (OPRS). SRSW and OPRS are being developed for a referenceless interferometer with a diffraction reference wave. The technique to minimize measurement errors is described. Developed SRSW and OPRS provide subnanometer optics measurement accuracy. The possibilities of improving the accuracy of interferometer measurements to the picometer level are discussed.

We demonstrate a three-port, light guiding and routing T-shaped configuration based on the combination of whispering gallery modes (WGMs) and micro-structured optical fibers (MOFs). This system includes a single mode optical fiber taper (SOFT), a slightly tapered MOF and a BaTiO3 microsphere for efficient light coupling and routing between these two optical fibers. The BaTiO3 glass microsphere is semi-immersed into one of the hollow capillaries of the MOF taper, while the single mode optical fiber taper is placed perpendicularly to the latter and in contact with the equatorial region of the microsphere. Experimental results are presented for different excitation and reading conditions through the WGM microspherical resonator, namely, through single mode optical fiber taper or the MOF. The experimental results indicate that light coupling between the MOF and the single mode optical fiber taper is facilitated at specific wavelengths, supported by the light localization characteristics of the BaTiO3 glass microsphere, with spectral Q-factors varying between 4.5 × 103 and 6.1 × 103, depending on the port and parity excitation.
