Abstract
In this paper, a method to eliminate the polarization dependent properties of fiber-to-planar waveguide couplers using a thin half-waveplate is proposed and demonstrated. The operation principle of the device is explained and the fabrication technology is presented. It is experimentally shown that the resonance wavelengths of the device are independent of the polarization state of input light.
Keywords
