Sapphire fibers: optical attenuation and splicing techniques

Optical properties of single-crystal sapphire fibers.

Single-crystal sapphire fibers have been grown with the laser-heated pedestal-growth method with losses as low as 0.3 dB /m at 2.94 ?m. With the incorporation of a computer-controlled feedback system, fibers have been grown with less than +/-0.5 % diameter variation, or +/-1.5 ?m for a 300- ?m fiber. The losses in these fibers have been reduced further through a postgrowth anneal at 1000 degree...

Arc-fusion Splicing Techniques for Holey Fibers

Recently, holey fibers (HFs) have attracted a lot of attention since the fibers can have properties that cannot be realized by traditional fibers with a corecladding structure 1). Applying HF to practical use requires the improvement of splice technique between HFs and between HF and a conventional single-mode fiber (C-SMF) in addition to the improvement in designing, manufacturing and measurem...

Emerging Optical CDMA Techniques and Applications

In this paper we present an in-depth review on the trends and the directions taken by the researchers worldwide in Optical Code Division Multiple Access (OCDMA) systems. We highlight those trends and features that are believed to be essential to the successful introduction of various OCDMA techniques in communication systems and data networks in near future. In particular we begin by giving a c...
