Abstract

The effects of extrinsic and inherent errors are analyzed for the integrated optical Givens rotation device. The extrinsic errors, caused by inaccurate voltage applied to the grating and inaccurate detection, are found to be important. The inherent errors caused by the propagation of these inaccuracies are detailed in algorithms for analog norm computation and in the QR algorithm for numerical linear algebra. A calibration procedure is developed to eliminate most of the errors.
