- 論文の詳細を見る
In this paper, we report a new interferometer, which can shift the fringe of a standing evanescent wave (SEW) continuously and infinitely. Combining a geometrical phase shifter, called a QHQ phase shifter (a half-wave plate sandwiched between two identical quarter-wave plates), with the Mach--Zehnder interferometer, we can modulate the SEW phase on the prism surface arbitrarily. Experimental results measured with a scanning near-field optical microscope show that this new interferometer provides faster and more stable phase shifting, compared to conventional one.
