    Abstract: A device including a plurality of epitaxial chips is disclosed. An epitaxial chip can have one or more of a light source and a detector, where the detector can be configured to measure the optical properties of the light emitted by a light source. In some examples, one or more epitaxial chips can have one or more optical properties that differ from other epitaxial chips. The epitaxial chips can be dependently operable. For example, the detector located on one epitaxial chip can be configured for measuring the optical properties of light emitted by a light source located on another epitaxial chip by way of one or more optical signals. The collection of epitaxial chips can also allow detection of a plurality of laser outputs, where two or more epitaxial chips can have different material and/or optical properties.

    Abstract: Methods for driving a tunable laser with integrated tuning elements are disclosed. The methods can include modulating the tuning current and laser injection current such that the laser emission wavelength and output power are independently controllable. In some examples, the tuning current and laser injection current are modulated simultaneously and a wider tuning range can result. In some examples, one or both of these currents is sinusoidally modulated. In some examples, a constant output power can be achieved while tuning the emission wavelength. In some examples, the output power and tuning can follow a linear relationship. In some examples, injection current and tuning element drive waveforms necessary to achieve targeted output power and tuning waveforms can be achieved through optimization based on goodness of fit values between the targeted and actual output power and tuning waveforms.
