Abstract

We report the fabrication and performance of a lensed photonic crystal fiber (PCF) designed as a compact but effective side-viewing optical imaging probe. The lensed-PCF probe was implemented in a single body without using any other fibers or additional optics. The beam expansion region and a focusing ball lens, necessary for a focuser, were simultaneously formed along a small piece of PCF by applying arc discharges. The side-viewing ability was provided by polishing the ball lens with a femtosecond laser to form a total internal reflection surface. The working distance and the transverse resolution of the fabricated single-body lensed-PCF were experimentally measured to be 570 and 6.8μm, respectively. With the proposed lensed-PCF probe, optical coherence tomography images of an in vitro biological sample were successfully obtained.

Light power of the beam reflected from a mirror and recoupled to the probe, measured with respect to the distance from the probe to the mirror. The working distance of the probe is defined as the position of the mirror where the maximum recoupling occurred, measured here as 570 μ m . The solid line at the bottom is the background power level.

Light power of the beam recoupled to the probe after being reflected from a sharp edge located at the working distance. The measurements were made with respect to the transverse movement of the sharp edge. The transverse resolution of lensed-PCF probe is defined as the 20%–80% bandwidth of the curve, measured here as 6.8 μ m .
