Abstract :
A hybrid fiber with an eccentric As2Se3 core and a PMMA cladding is tapered to a submicron diameter to achieve ultra high birefringence and a high nonlinearity. The high birefringence is induced by having the As2Se3 core eccentric with respect to the circular PMMA cladding symmetry and the high nonlinearity is induced from a tightly confining As2Se3 core. Microwires with high group birefringence up to bg=0.018 and a high waveguide nonlinearity γ = 180 W-1m-1 are demonstrated.
