Abstract
A microstructured optical fiber for transmitting optical signals comprised of light, the optical fiber comprising: a core region disposed about a longitudinal centerline and having a refractive index profile with a first refractive index, and a cladding region surrounding the core region, the cladding region comprising an annular void-containing region comprised of non-periodically disposed voids; wherein maximum void diameter in nm is given by Dmax and the maximum void length in cm is not greater than 2.5×105×(dmax)−1.7.
Claims26
A microstructured optical fiber for transmitting optical signals comprised of light, the optical fiber comprising:
- a core region disposed about a longitudinal centerline and having a refractive index profile with a first refractive index, and
- a cladding region surrounding the core region, the cladding region comprising an annular void-containing region comprised of non-periodically disposed voids;
- wherein maximum void diameter in nm is dmax, and the maximum void length in cm is not greater than 2.5×105×(dmax)−1.7.
A method of connectorizing an optical fiber having a core, a cladding with non-periodically disposed voids, and at least one of a coating and a buffer, the method comprising the steps of:
- (i) stripping a length of at least one of the coating and the buffer to expose a portion of the optical fiber;
- (ii) cleaving the exposed optical fiber portion to form a cleaved end-face, said cleaved end-face comprising voids with diameter not greater than maximum void diameter (in nm) dp and maximum void length (in cm) of not greater than 2.5×105×(dmax)−1.7;
- (iii) polishing said cleaved end-face to form a polished fiber end face.
A method of polishing microstructured optical fiber having a core region disposed about a longitudinal centerline and having a refractive index profile with a first refractive index, and a cladding region surrounding the core region, the cladding region comprising an annular void-containing region comprised of non-periodically disposed voids, said method comprising the steps of:
- (i) cleaving the optical, thereby forming a cleaved end face, the cleaved end face containing exposed voids with maximum void diameter dmax in nm, and the maximum void length in cm of not greater than 2.5×105×(dmax)−1.7;
- and
- (ii) polishing said cleaved end face.
