Abstract: In this work, we report a simple and easily adaptable technique of lateral micro-machining of Photonic Crystal fibers (PCFs) using modulated CO2-laser in conjunction with electrical arc system. The technique is controlled, convenient and precise over wide dimensions (50-250 mm). Lateral access to the holes of PCF provides additional flexibility for sensitive real time detection of gases such as green-house gases. Long period gratings are made in PCF through inscription of micro-grooves for sensitive detection of longitudinal strain. A unique and versatile PCF based probe for possible endoscopic Optical Coherence Tomography (OCT) applications is reported.

 

Keywords: Micro-machining, CO2 laser, Lateral access, Optical coherence tomography, Micro-grooves
