Abstract
A two-beam polarization interferometer for measuring wavelength changes of a tunable semiconductor laser was designed, built and tested. This interferometer uses a λ/8 waveplate made from Liquid Crystalline Polymer in order to generate two output signals in quadrature. The λ/8 waveplate can be manufactured either on a beamsplitter face or on the mirror surface, reducing the cost and complexity of the optomechnical assembly. Experiment results show that a resolution of 2pm was attained for the wavelength range 628-635nm. The range of operation of such an interferometer can be extended if the wavelength-dependent Heydemann correction is used.
