Abstract
Embodiments of the invention are directed to an integrated optogenetic device. The integrated optogenetic includes a substrate layer having a first substrate region and a second substrate region. The device further includes a first contact formed over the substrate layer in the first substrate region and a second contact layer formed over the substrate layer in the second region. In addition, the device includes a light-emitting diode (LED) structure communicatively coupled to the first contact layer and a biosensor element communicatively coupled to the second contact layer. The first contact layer is configured to operate as a bottom contact that provides electrical contact to the LED structure. The first contact layer is further configured to be substantially lattice matched with the substrate layer and a bottom layer of the LED structure.
