Paper Abstract

We propose an integrated optical polarization detection device for magneto-optical disk pickups. The device has a prism coupler and a TE/TM mode splitter which is monolithically integrated on a silicon substrate with p-i-n photodiodes and two optical waveguides with different effective indices of refraction. These two waveguides are connected at two tapered transition regions. This paper describes the device fabrication techniques and the performance of each element integrated in the device. The optical waveguide TE/TM mode splitter is shown to have wide tolerance for wavelength change, fabrication error, or deviation from designed incident angle.
