Loss analysis of air-core photonic crystal fibers [PDF]
, 2003 By using a multipole moment approach, we analyze the loss of an air-core photonic crystal fiber and demonstrate that it is possible reduce the transmission loss that is due to photon radiation leakage through the photonic crystal cladding to a level ...
