Abstract
In this thesis we propose an innovative approach of designing and implementing a temperature compensated two-mode optical fiber interferometer in a control system of stabilizing the wavelength of a laser. We give the procedure for designing this interferometer along with the experimental results and explain the practical limitations on the performance of this interferometer. Further we elaborate the need and design of a quadrature phase detection technique for measuring the small phase shifts between the spatial modes of the fiber. We also analyze that the polarization dependence of the interference between differing spatial modes of an optical fiber under axial strain and show that it can be experimentally determined purely from the far-field intensity patterns of those modes.
