1. Optical cryptography through analog control of amplitude and delay of spectral slices: anlysis for NRZ and DQPSK signals. / Criptografia Ãptica mediante controle analÃgico da amplitude e do atraso de fatias espectrais: anÃlise para sinais NRZ e DQPSK.
This work investigates a technique to encrypt the optical signal for Transparent Optical Network, TON, in order to safeguard the confidentiality and guarantee the security of informations that are transmitted through the Telecommunications Network. The technique is assessed on the physical layer of the reference model for open systems interconnection, OSI, a

2. Systemic analysis of noise penalties all-optical network / AnÃlise sistÃmica das penalidades de ruÃdo nas redes Ãpticas transparentes
In this thesis, the routing and wavelength assignment processes are addressed. Besides of considering the network layer resources (number of available wavelengths in a link), the impact of physical layer effects in the transmitted optical signals is analyzed for both processes. The optimization of the wavelength assignment process is obtained by minimizing t
