Selectively liquid-filled photonic crystal fibers for optical devices.
We have theoretically investigated the propagation properties of two kinds of selectively liquid-filled PCFs. For internally liquid-filled PCFs, the outer air-hole layers function as the second cladding to reduce the penetration of the light field while the inner liquid-hole layers can still induce the tunable PBG effect. The complementary structures, externally liquid-filled PCFs, can be used in long-period fiber gratings to decrease the utilization of the lossy liquids and remain single-mode operation for the existence of the inner air-hole layers. The confinement losses of both selectively liquid-filled PCFs are shown to be efficiently reduced due to the outer or inner air-hole layers, which is quite useful for further applications.
