Low bending loss and effectively single-mode all-solid photonic bandgap fiber with an effective area of 650 μm 2
2012
A large-mode-area all-solid photonic bandgap fiber with a seven-cell core and
five high-index rod rings is investigated. Numerical simulations show that an
effective area of more than 500 μm2, a bending loss
of less than 0.1 dB/m at a bending radius of 10 cm and
effectively single-mode operation can be achieved simultaneously. A core diameter of
44.8 μm and an effective area of 650 μm2
at 1064 nm are achieved in a fabricated fiber. Bending loss at 1064 nm is
0.09 dB/m at a bending radius of 7 cm. Effectively single-mode
operation is also realized at a bending radius of 10 cm.
