Conversions among binary optical modulation formats

Conversions among binary optical modulation formats.

We study the intrinsic relations and conversions among different binary modulation formats such as non-return-to-zero (NRZ), return-to-zero (RZ), carrier-suppressed return-to-zero (CSRZ), differential-phase-shift-keying (DPSK), duobinary, and alternate-mark-inversion (AMI). In particular, we experimentally demonstrate the new conversion from CSRZ to duobinary using a Mach-Zehnder delay interfer...

Performance Improvement from Optical Modulation Formats in Practical Systems

Performance of Modulation Formats on Dwdm Optical Systems

The need for higher transmission rate in Dense Wavelength Division optical systems necessitates the selection of a suitable modulation format for the efficiency of the optical system and has been a key issue in recent research (Vassilieva et al 2001). Generally modulation formats are classified into On Off Keying (OOK) and Phase Shift Keying (PSK) techniques (Idler et al 2003). Over the last fe...
