Under the proper design conditions, an arrayed waveguide grating is capable of producing high repetition rate pulse trains from a lower rate short pulse source.  The temporal intensity profile may be equalized to generate a flat-topped pulse train by tailoring the design of the AWG.

1 THz repetition rate bursts of short pulses at multiple spatially separated output channels are demonstrated from a single short pulse source laser and an arrayed waveguide grating designed to have a free spectral range less than the bandwidtth of the source laser.

EXAMINING ELECTRONIC SURVEILLANCE IN THE WORKPLACE:A REVIEW OF THEORETICAL PERSPECTIVES AND RESEARCH FINDINGS

CERIAS TR 2001-32

Almost three fourths of major U.S. firms admit that they engage in one form or another of electronic surveillance (American Management Association, 2000). At the same time,  concern over the negative effects of electronic surveillance is raising. The paradox of electronic surveillance is that it is much used and little understood. This paper is an attempt to facilitate and stimulate research into electronic surveillance.  It summarizes up-to-date information on the pervasiveness and the noted effects of electronic surveillance. It proceeds to review academic studies that have focused on this phenomenon and finally, it proposes two other theoretical perspectives that may explain behavior-related effects of electronic surveillance -  equity theory, and a communication-oriented approach that focuses on surveillance and responses to it as socially constructed acts of discipline and antidiscipline.

"WHAT ARE YOU REALLY SAYING TO ME?" ELECTRONIC SURVEILLANCE IN THE WORKPLACE

CERIAS TR 2001-23

This paper discusses the meta-communicative aspects of electronic surveillance in the workplace, whether it is used for information security or other purposes. Both quantitative and qualitative results of survey work are reported to support the contention that the use of electronic surveillance is itself a communicative act and that the employees who are being surveilled interpret it—and respond to it—as such.
