- Abstract
The authors experimentally demonstrate a modulating retro‐reflector based on electro‐optical in‐phase quadrature modulator and test it in an atmospheric cell simulated atmosphere environment by using 80 Gb/s polarisation‐multiplexing quadrature phase‐shift keying (Pol‐MUX QPSK) signals. At the BER of 1 × 10−3, the power penalties of the x‐ and y‐polarisation signals are both <1.1 dB when the temperature difference in the atmospheric cell is <250°C.
