Abstract :
Developments in neuroprosthetics have lead to applications with high channel counts, thus increasing the need for high bandwidth telemetry systems to transmit data out of the body. Optical telemetry is a promising implantable telemetry solution, and data rates and power consumption criteria are being established. This paper presents the performance of a laser diode-based system in various operating conditions. This system transmits at data rates up to 16 Mb/s through a skin thickness of 4 mm while achieving a BER of 1E-9 with consumption of 10 mW or less.
