Photonic crystal fiber design for broadband directional coupling

Research output: Contribution to journalJournal articleResearchpeer-review

Abstract

A novel design for a broadband directional coupler based on a photonic crystal fiber is investigated numerically. It is shown that suitable index-depressing doping of the core regions in an index-guiding twin-core photonic crystal fiber can stabilize the coupling coefficient between the cores over an extremely broad (octave-spanning) frequency range.
