Abstract : This paper descibes an all-optical label swapping for the photonic label switching router(LSR). The optical code routing photonic LSR in which label is mapped onto an optical code is one of the most promsing photonic network technologies. It utilizes such unique fearures of optical code division multiplexing(OCDM) as asynchronous transmission, tell-and-go access protocol, and high degree of scalability. In practical photonic LSRs, all optical code conversion will play an important role. All-optical code conversion of 10Gbit/s binary phase-shift keying(BPSK) codes by use of cross-phase modulation (XPM) in an optical fiber without wavelength-shift is proposed for the photonic LSR and experimentally demonstrated.
