✦ Synopsis

Original analysis and results are gi¨en for an optically ( ) preamplified digital pulse-position-modulation PPM recei¨er with an impro¨ed electrical-domain filtering regime consisting of a matched filter cascaded with a pulse-shaping network. Impressi¨e sensiti¨ity results are reported, with the 21.54 photonsrbit predicted at 622 Mbitrs, surpassing both an equi¨alent optically preamplified on-off keyed nonreturn-to-zero ( ) ( )
