Capacity limit of the noiseless, energy-efficient optical PPM channelIt is shown that even though the capacity per photon can be made to increase without bound, the capacity per channel use (for best power efficiency) is always less than 2 nats per symbol. Furthermore, it approaches 2 nats per symbol as the bandwidth expansion factor goes to infinity. Previously announced in STAR as N82-20121
