Generalized Stokes parameters shift keying approach to multichip differential phase encoded optical modulation formats.

Conventional and advanced modulation formats that simultaneously modulate two or more of the optical attributes of phase, amplitude, and polarization and/or utilize observation intervals longer than two chips (time slots) are designed by using a unified interpretation as signaling by means of generalized Stokes parameters. In particular, the new paradigm is applied to the recently introduced multichip extension of optical differential phase shift keying.

Quantum key distribution over a fiber-optic channel by means of pulse position modulation.

New methods are proposed for extending the range of fiber-optic one-way quantum key distribution (QKD), inspired by classical optical communication formats. A new time-domain technique based on pulse position modulation (PPM) is combined with differential phase-shift keying to optically implement a six-state protocol. Finally, some recently proposed PPM schemes are critically reviewed and applied to synthesize a new QKD asymmetric optical realization, applicable to local or metropolitan area networks.
