Abstract:
An anti-resonant hollow-core fiber comprising a first tubular, cladding element which defines an internal cladding surface, a plurality of second tubular elements which are attached to the cladding surface and together define a core with an effective radius, the second tubular elements being arranged in spaced relation and adjacent ones of the second tubular elements having a spacing therebetween, and a plurality of third tubular elements, each nested within a respective one of the second tubular elements.

Claim (Index 70):
The fiber of  claim 54 , wherein the second, outer tubular element of at least one of the nested tubular arrangements has a wall thickness t 1  which is different to that of a wall thickness t 2  of the second, outer tubular element of at least one of the other nested tubular arrangements, whereby the fiber is phase bi-refringent and polarizing-maintaining and/or polarizing, optionally the relationship of the wall thickness t 1  of the outer tubular element of the at least one of the nested tubular arrangements to the wall thickness t 2  of the outer tubular element of the at least one other of the nested tubular arrangements is 0.5t 2 <t 1 <t 2  or 1.5t 2 >t 1 >t 2 , optionally 0.4t 2 <t 1 <t 2  or 1.4t 2 >t 1 >t 2 , optionally 0.3t 2 <t 1 <t 2  or 1.3t 2 >t 1 >t 2 , optionally the relationship of the wall thickness t 1  of the outer tubular element of the at least one of the nested tubular arrangements to the wall thickness t 2  of the outer tubular element of the at least one other of the nested tubular arrangements is t 1 <0.9t 2  or t 1 >1.1t 2 , optionally the second, outer tubular elements of first and second of the nested tubular arrangements have a wall thickness which is different to that of the wall thickness of the second, outer tubular element of at least one other of the nested tubular arrangements, optionally the first and second tubular arrangements are disposed in generally opposed relation, optionally diametral relation, optionally comprising two, three, four, five, six, seven or eight nested tubular arrangements, optionally comprising four nested tubular arrangements, wherein a first pair of the nested tubular arrangements are arranged in a first substantially common direction and a second pair of the nested tubular arrangements are arranged in a second substantially common direction which is substantially orthogonal to the first substantially common direction, optionally the effective radius of the core of the fiber is at most about 15 times the wavelength \u03bb of the source, optionally at most about 7 times, optionally at most about 5 times, optionally the wavelength \u03bb is about 0.5, 0.8, 1.06, 1.55 or 2 \u03bcm.
