Optical fiber for broadband optical devices and optical fiber devices using thereof |
摘要 |
The present invention relates to an optical fiber having a normalized frequency applicable to a broadband optical device, and to a broadband, polarization-independent, low-loss optical fiber device made by using the aforementioned optical fiber. The optical fiber of the present invention has a normalized frequency value V, structural parameters of which including a core radius, a core refractive index and a cladding refractive index are adjusted to minimize the beat dispersion between first and second modes in a predetermined frequency range. Various optical fiber devices may be achieved if the aforementioned optical fiber is used along with acoustic wave generating means and a mode dropper or a mode selective coupler.
