ON-CHIP PHOTONIC INTEGRATED CIRCUIT OPTICAL VALIDATION

Abstract:

Photonic errors in a photonic integrated circuit can be imaged using an on-chip light source integrated in a photonic layer of the circuit. The on-chip light source can generate light at wavelengths that propagates through one or more substrate layers to an image sensor sensitive to the wavelength range. The on-chip light source can be tunable and provide different power settings that can be utilized to detect different types of optical errors in the photonic integrated circuit.
