Abstract

To use optical techniques deep in tissue, implantable microdevices which can collect and deliver light with high efficiency are needed. Flexible polymer devices can reduce tissue damage. Here, we demonstrate a fully-flexible, low-loss (3.2 dB/cm @ 680 nm), broadband (450-680 nm) integrated photonic platform composed entirely of Parylene C and PDMS. Using this platform, we demonstrate devices with an array of 6 waveguides and 1.3 cm total length. We integrate bare laser diode chips (220 x 220 μm, λ= 680 nm) to realize a light delivery system for optogenetics. Simulation, characterization, and biological demonstration will be discussed.
