Abstract

We have proposed an optical coherence domain reflectometry by synthesis of coherence function (OCDR), for high spatial-resolution measurements of optical waveguide devices. We present the principle of the OCDR and the recent experimental results of the OCDR with spectrum spacing control of many lines. A three-electrode DFB laser diode with wide frequency tunable range is used as the light source to improve the resolution. The spatial resolution of 3 to approximately 4 mm in air has been obtained. Furthermore, overall effects of the performance deterioration factors are theoretically considered.
