Experimental setup (top view). LD: tunable laser diode; M: mirror; WP: wedge plate; HWP: half wave plate; QWP: quarter wave plate; PBS: polarizing beam splitter; PD: photodiode; FC: fiber coupler; SMF: single-mode fiber. PBS3 and HWP4 positioned at the output were inserted when the polarization transmission properties of the fiber shown in Fig. 2 were measured.
Polarization-dependent intensity of the output laser power obtained by varying the tilting angle of the linearly polarized probe input light. The experimental data were fitted with sine functions (solid lines) to derive visibilities.
Transmission spectra of a tapered fiber coupled with a microsphere resonator. Appropriate offsets were added to the data with and for the sake of clarity.
Normalized depth of the dips, A16 (square) and B11 (circle) as a function of the input polarization. The experimental data were fitted with sinusoidal curves.
