We propose and demonstrate a cost-effective liquid refractive index (RI) sensor in polymer materials by employing a Mach-Zehnder interferometer (MZI) formed with the conventional strip waveguide. The proposed sensor can attain high sensitivity by choosing a suitable reference arm length to reduce optical path difference (OPD) between the two arms of the employed MZI. Our fabricated devices, which have the same sensing arm length of 7900 &#x00B5;m but different reference arm lengths of 7900.0, 7942.5, 7950.9, 7962.2, and 7969.5 &#x00B5;m, respectively, exhibit the maximum RI sensitivities of 33662.8 nm&#x002F;RIU, and almost the same detection range (DR) of 0.0041 &#x00B1; 0.0002 RIU.
