초록/요약
We present an LED-waveguide-based neural probe array with the highest total light power delivery from a single commercial LED. A separable configuration between the LED and the waveguide has been proposed and verified experimentally for a disposable probe tip. The system comprises of a disposable MEMS optrode array and a reusable unit. The optrode array consists of a 4 x 4 array of 6 mm-long optical fibers assembled with thermally reflowed square-shaped glass microlenses. The reusable unit includes a domed top LED and driving circuitry. Measured light delivery efficiency of the optrode array and the total power efficiency of the probe were -10.6 dB and -21.6 dB, respectively. (C) 2018 Elsevier B.V. All rights reserved.
