University of Tokyo, Department of Electrical Engineering and Information Systems, Tokyo, Japan
Opt Express 18:26929-36. 2010..We validate our multi-impairment monitoring algorithm by dual-polarization quadrature phase-shift keying (QPSK) transmission experiments...
- Stable source of high quality telecom-band polarization-entangled photon-pairs based on a single, pulse-pumped, short PPLN waveguideHan Chuen Lim
