ABSTRACT:
A porous optical fiber provided with air holes and a method for manufacturing the same are disclosed. The porous optical fiber includes a core having a first refractivity extended in a longitudinal direction, an external cladding layer having a second refractivity surrounding the core, and an internal cladding layer having a third refractivity formed between the core and the external cladding layer and provided with a plurality of air holes scattered therethrough.
