Aspects of burst errors in digital telecommunications transmission systems
, 1994 This work, and thesis, explores an alternative approach to the performance monitoring of digital communications systems. The objectives are to identify the structure of burst error activity and sense any subsequent changes in this structure. This research project investigates the use of the autocorrelation function of the error activity.

Advanced Science, EarlyView.Schematic diagram of wavelength‐tunable pulsed laser based on metafiber‐FP (Fabry‐Perot). The alcohol solution is filled inside the FP cavity to simultaneously form a spectral filter and a saturable absorber. By adjusting the refractive index value and temperature inside the cavity, the tunable filtering effect is introduced to realize wavelength ...
