摘要： A photonic integrated device (1) comprises a waveguide (14, 16) of semiconductor material and a detector (26) for measuring optical power of light travelling along the waveguide (14, 16). The detector which is monolithically integrated into the device measures a photocurrent on an electrode (26) which has been generated in the waveguide by two photon absorption.
