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.
