Co-axial dual-core resonant leaky fibre for optical amplifiers [PDF]
, 2008 We present a co-axial dual-core resonant leaky optical fibre design, in which the outer core is made highly leaky. A suitable choice of parameters can enable us to resonantly couple power from the inner core to the outer core. In a large-core fibre, such

SPIE Proceedings, 1987 Optical fibres are making ever-increasing inroads into areas traditionally satisfied by older, more established technologies. In particular, sensors which rely on the external modulation of the properties of an optical fibre (intrinsic sensors) are receiving much attention since they can be made extremely sensitive and can be used for distributed ...

A Cladding-Pumped Device for Modal Gain Equilization Based on Rippled Few Mode Fiber
IEEE Photonics JournalTo achieve mode-division multiplexing (MDM) for long-distance transmission, the development of signal amplifiers, such as erbium-doped fiber amplifiers (EDFA), is crucial. As a solution for EDFA, cladding pump has gained attention due to its low cost and
