Long period gratings formed in depressed cladding fibres

Long period gratings formed in depressed cladding fibres
Long period gratings formed in depressed cladding fibres
In a single mode fibre of a depressed cladding design, the LP11 mode is leaky but can propagate over a short length of fibre. This leaky LP11 mode instead of the conventional cladding modes can be used in long period gratings, with two extra benefits, I) a larger overlap, giving stronger coupling and II) coupling is insensitive to the glass-air interface therefore packaging is easier.

Abstract

In a single mode fibre of a depressed cladding design, the LP11 mode is leaky but can propagate over a short length of fibre. This leaky LP11 mode instead of the conventional cladding modes can be used in long period gratings, with two extra benefits, I) a larger overlap, giving stronger coupling and II) coupling is insensitive to the glass-air interface therefore packaging is easier.
