The present invention discloses a preform assembly and a method for drawing a multicore optical fibre and a holey fibre. Particularly, the preform assembly includes a hollow cylindrical tube, a plurality of discs stacked inside the hollow cylindrical tube and a plurality of core rods inserted in a plurality of through holes in each of the plurality of discs.

Preform assembly for drawing multicore or holey optical fibre and method of manufacturing thereof

The present disclosure provides an optical fibre. The optical fibre includes a core extended from a central longitudinal axis to a first radius r. Further, the optical fibre includes a first trench region extended from a second radius rto a third radius r, a second trench region extended from the third radius rto a fourth radius rand a cladding region extended from the fourth radius rto a fifth radius r

Cutoff shifted optical fibre

The present disclosure provides an optical fibre. The optical fibre includes a core region, a primary trench region and a secondary trench region. The core region has a radius r. In addition, the core region has a relative refractive index &#x394;. Further, the primary trench region has a relative refractive index &#x394;. Furthermore, the primary trench region has a curve parameter &#x3b1;. Moreover, the secondary trench region has a relative refractive index &#x394;. Also, the secondary trench region has a curve parameter &#x3b1;.
