GeSn Infrared Photodiode (PD) for Optical Wireless Communication (OWC) at 2 μm Wavelength Band
We demonstrate a germanium-tin (GeSn) photodiode (PD) for optical-wireless-communication (OWC) applications. It can detect a 400 Mbit/s on-off-keying (OOK) modulated signal fulfilling the pre-forward-error-correction (FEC) threshold (i.e. bit-error-rate, BER = 3.8 × 10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup>).
