TL;DR: Chalcogenide glass fibers based on sulphide, selenide, telluride, and their rare earth doped compositions are being actively pursued both at the Naval Research Laboratory in Washington, D.C. and worldwide.

TL;DR: In this article, a single-mode chalcogenide optical fiber was fabricated by a double crucible technique and the optical loss of this fiber was measured by a standard cutback technique using an FTIR spectrometer and also using an F-center laser.

TL;DR: Fiber strengths are reasonable for many short length applications, but improved processing will lead to stronger fibers for long length applications.

TL;DR: Chalcogenide glass fibers based on sulphide, selenide, telluride and their rare earth doped compositions are being actively pursued at the Naval Research Laboratory (NRL) as well as world-wide as mentioned in this paper.

TL;DR: Fiber-optic couplers represent one of the fundamental building blocks for sophisticated optical-fiber devices, and though some investigations have been done with core-only chalcogenide fiber, no fused devices have been made for infrared (IR) operation beyond 1.55 /spl mu/m.
