Abstract
An optical fiber apparatus includes an optical fiber, and a demultiplexing/multiplexing unit for demultiplexing or multiplexing at least a light wave of at least a wavelength with a sufficiently narrow wavelength spectrum that is determined by a resolving power thereof, such as a Fabry-Perot etalon. The demultiplexing/multiplexing unit is provided or formed directly on at least an end face of the optical fiber. An optical detector array including a plurality of optical detectors for detecting demultiplexed light waves may be provided on a light emergence surface of of the demultiplexing/multiplexing unit.
