ABSTRACT:
In accordance with the invention, an optical fiber system is provided with a tapered fiber device for filtering, wavelength shift detecting, or switching. Specifically, applicant has discovered that a multiclad single mode optical fiber with a fundamental mode cutoff can be tapered to form a compact component useful in optical fiber systems, e.g. a filter in telecommunications systems, a wavelength shift detector in sensing systems, or a switch in any optical system.
