Wavelength conversion of 160 Gbit/s OTDM signal using bismuth oxide-based ultra-high nonlinearity fibre

All optical wavelength conversion via cross phase modulation in chalcogenide glass rib waveguides

“…This is primarily because the As 2 S 3 rib waveguide length (5 cm) is significantly shorter than other demonstrations (e.g. 5 km of silica [15], bismuth oxide [10] or As-Se [8] fiber). Figure 4(c) shows the filtered spectra of the pulses converted to three different wavelengths (1556.4 nm, 1560.5 nm and 1564.7 nm).…”

All-optical Signal Processing Using Specialty Fibers

“…A range of high speed OTDM signal processing devices have been experimentally demonstrated with only 1-m length of the fiber: for example, 160 Gbit/s-OTDM demultiplexer [15], 160-Gbit/s OTDM add/drop multiplexer [16], 160-Gbit/s wavelength converter [17], 80-Gbit/s clock recovery [18], 40Gbit/s logic gates [19], 2R regenerator [20], and 2x2 switch [21] …”

All-Optical Wavelength Conversion of 80 Gb/s Signal in Highly Nonlinear Serpentine Chalcogenide Planar Waveguides

“…In this regard, chalcogenide glasses have attracted significant attention due to their large Kerr (n 2 ) nonlinearity [1] (100's × silica glass) and low to moderate two-photon absorption. Whilst all-optical wavelength conversion has been demonstrated in Bi 2 O 3 [2] and As 2 Se 3 [3] fiber, enhanced performance can be achieved using chalcogenide waveguides [4] as the combined high nonlinearity and intrinsic response time of < 100 fs enables the realization of the multi-functional, monolithically integrated photonic chips capable of processing of high bandwidth signals. In this paper, we achieve broadband 80 Gb/s wavelength conversion (×8 increase compared to earlier work [4]) in a long, ultra low-loss (0.05 dB/cm) serpentine shaped, chalcogenide glass rib waveguide using cross-phase modulation (XPM) side-band filtering.…”
