A novel design of PCF for supercontinuum source to detect oral cancer using OCT

A PCF structure that is filled up with chloroform in its core, is optimized for generating broadest possible supercontinuum spectrum which centers at 1310 nm. It has been found that a chloroform filled PCF having airholes of diameter 1.5μm and cladding of pitch 1.2μm is capable producing broadest supercontinuum light at a shorter distance than as silica core PCF can do. The generated supercontinuum can be used as a light source in an optical coherence tomography(OCT) system to detect oral cancer with a resolution of 964 nm.
