Simultaneous label erasure and rewriting using a single reflective semiconductor optical amplifier for DPSK/ASK optical label switching

Abstract

In future all-optical packet networks, optical label switching technology is expected to be a promising candidate for fast and accurate data packet transmission [1, 2]. To implement such networks, a simple yet low cost optical label swapping technique should be realized at the intermediate nodes. Many research efforts have been developed, based on the promising technique of orthogonal label modulation [3] due to its simple design in optical label swapping [4]. In recent years, the nonlinear phenomenon in semiconductor optical amplifiers has been widely utilized for applications in optical label erasure [5]. Recent advances in the fabrication of reflective semiconductor optical amplifiers (RS..
