Abstract

Absolute temperature measurements of integrated photonic devices can be accomplished with integrated bandgap temperature sensors located adjacent the photonic devices. In various embodiments, the temperature of the active region within a diode structure of a photonic device is measured with an integrated bandgap temperature sensor that includes one or more diode junctions either in the semiconductor device layer beneath the active region or laterally adjacent to the photonic device, or in a diode structure formed above the semiconductor device layer and adjacent the diode structure of the photonic device.
