Characterization of the chirp in semiconductor laser under modulation (subscription required)

In this paper we present, shortly, a study of the chirp induced in direct modulated DFB laser. Our description of the chirp is based, first on analytical resolution of the rate equations, and second on a simulation of a heterodyne system with the Optisystem software.

Design and simulation of a novel phase-encoded OCDMA system

The security of optical code division multi-access (OCDMA) system was analyzed, and the results indicate the hidden trouble of security. A scheme of multi-codes to be transmitted single-user information has been proposed, and single-user eavesdropping model has been simulated.
