PRECISION SIDE-POLISHED FIBERS WITH A LONG INTERACTION LENGTH

We succeeded in fabricating precision side-polished fibers embedded in silicon V-grooves and then polished six fibers using a home-made poli sher. The control of the polishing depth of the side-polished fibers w as as accurate as +/-0.25 mu m. Another merit of our polished samples was their negligible losses even though tile effective interaction len gths were long. Experimental calibrations of our samples agreed with t heoretical results.
