How Quantum Efficiency for Modulation affects performance of Optical Wireless

How would you benchmark a LiFi system? Just on the bandwidth of the photonic components? Ever thought about specifying photons per bit, or watts per square meter of coverage? Several of our recent papers report that received signal strength is at least as important as bandwidth (GHz) to boost the bit rate (Gbit/s). And then the quantum efficiency becomes a key parameter to improve. That makes it particularly interesting to note that the Quantum Efficiency as we know it for (DC) illumination can differ quite a lot from the "differential" Quantum Efficiency for modulation. A key step towards making LiFi greener, more efficient and faster.
