All-optical modulation format conversion from NRZ-OOK to PSK-Manchester using SOA-MZI
نویسندگان
چکیده
Proposed and demonstrated is an all-optical modulation format conversion from a non-return-to-zero on-off keying (NRZ-OOK) signal to a phase-shift keying (PSK)-Manchester format signal using a semiconductor optical amplifier based Mach-Zehnder interferometer (SOAMZI). In the experiment, a 2.5 Gbit/s PSK-Manchester format signal was obtained from a NRZ-OOK signal and a 50 km error-free transmission of the converted PSK-Manchester format signal was achieved. In addition, the feasibility of the conversion at a higher data rate using SOAs with fast phase recovery was investigaged.

We present a new TDM/WDM PON scheme utilizing PSK (phase shift-keying) at 10 Gbit/s per λ-channel as the modulation format along the feeder line and an SOA (semiconductor optical amplifier) as the amplifying component at the remote node. One single DLI (Delay Line Interferometer) converts all λ-channels from PSK to OOK (on-off keying), the modulation format which is used along the access line a...

We propose a scheme to achieve regenerative format conversion from a distorted non-return-to-zero-on-off-keying (NRZ-OOK) signal to a return-to-zero-binary-phase-shift-keying (RZ-BPSK) signal of high quality in an integrated device. This proposal is achieved by employing an interferometer on a silicon chip with a coupled ring resonator optical waveguide embedded in one arm. In this scheme the a...
