Multiwavelength conversion based on reflective semiconductor optical amplifiers

In this contribution the routing capabilities of time/wavelength codes in Optical Code Division Multiple access are observed by means of the study of two devices for achieving the wavelength part code conversion. Multi-wavelength conversion will be achieved by using a Semiconductor Optical Amplifier and a Reflective Semiconductor Optical Amplifier. The conversion results for the two devices will be characterized and compared in terms of applicability to the conversion in hands and to the referred application.

Optical communication groups at University of Aveiro and Institute of Telecommunications--Aveiro pole

This paper summarizes the research activities of the optical communications group at University of Aveiro and Institute of Telecommunications-Aveiro pole. Several activities like clock recovery systems, both electrical and all optical, electrical equalizers for very high bit rate DST systems, post-detection filters for multigigabit optical receivers, soliton systems, simulation work on WDM, DST, EDFA and short pulse generation for high bit rate systems are presented.
