Abstract

There is provided a photonic integrated apparatus for determining an orientation and/or a position of an optical waveguide, by measuring a relative intensity and a relative phase difference of the probe light signal incident on a sensor array. The phase profile of the probe light signal projected spatially on the sensor array is particularly sensitive to small changes in the optical probe's orientation and distance. The apparatus measures the relative intensity and relative phase difference of the probe light signal incident on a sensor array. A photonic integrated sensor circuit comprises the sensor array and one or more optical interferometric circuits. Changes in the sensed relative intensity and relative phase difference of the probe light signal, as sampled by the sensor array, indicate variations in the relative orientation and/or distance between the optical waveguide and the sensor array.
