All-optical regenerative NRZ-to-RZ format conversion using coupled ring-resonator optical waveguide.
This paper proposes a scheme for format conversion from a distorted non-return-to-zero (NRZ) signal to a high-quality return-to-zero (RZ) signal, using the nonlinearity in a coupled ring-resonator optical waveguide (CROW) on a silicon chip. In this method, a distorted NRZ signal is amplified and fed into the CROW together with an RZ pulse train. The CROW performs as a nonlinear step gate for th...
متن کاملAll-optical regenerative NRZ-OOK-to-RZ-BPSK format conversion using silicon waveguides.
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...
متن کاملSimultaneous RZ-OOK to NRZ-OOK and RZ-DPSK to NRZ-DPSK format conversion in a silicon microring resonator.
Simultaneous RZ-OOK to NRZ-OOK and RZ-DPSK to NRZ-DPSK modulation format conversion in a single silicon microring resonator with free spectral range equal to twice the signal bit rate is experimentally demonstrated for the first time at 41.6 Gb/s. By utilizing an optimized custom-made microring resonator with high coupling coefficient followed by an optical bandpass filter with appropriate band...
متن کاملAll-optical modulation format conversion from NRZ-OOK to PSK-Manchester using SOA-MZI
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 transmiss...
متن کامل10 Gbit/s all-optical NRZ-OOK to RZ-OOK format conversion in an ultra-small III-V-on-silicon microdisk fabricated in a CMOS pilot line.
We report the demonstration of an all-optical, bias free and error-free (bit-error-rate ~10(-12)), 10 Gbit/s non-return-to-zero (NRZ) to return-to-zero (RZ) data format conversion using a 7.5 µm diameter III-V-on-silicon microdisk resonator. The device is completely processed in a 200 mm CMOS pilot line. The data format conversion is based on the phenomenon of pulse carving of an NRZ optical da...
