commercialized SI POF for the first time with trade name of ‘‘Eska’’ in 1975.
Other major POF manufacturers, Asahi Chemical and Toray, followed in 1980s.
Experimental work on loss reduction of PMMA-core SI POF was conduc ted in
1980s by Kaino et al [1]. They also reported low-loss SI POF experimentally
obtained by employing perdeuterated PMMA [2]. Impressive results were obtained
during the end of 1980s [3, 4].
