This paper describes the use of optical time lenses for optical signal processing of advanced optical data signals. Examples given include 1.28 Tbaud Nyquist channel serial-to-parallel conversion and spectral magnification of OFDM signals.
We present a numerical bit-error rate investigation of 160–640 Gbit/s serial-to-parallel conversion by four-wave mixing based time-domain optical Fourier transformation, showing an inverse scaling of the required pump energy per bit with the bit rate.
Simultaneous transient suppression of four transient-impaired 40 Gbit/s RZ-ASK WDM channels is demonstrated. Sensitivity improvements are in excess of 5 dB and transmission penalties are significantly reduced.
A Raman-based bi-directional long-reach passive optical network (PON) link was proposed and had shown to be very robust toward WDM channel add/drops and therefore look promising for future high-capacity fiber-to-the-premises (FTTP) systems with bursty traffic. Penalty measurements on a weak data channel, under the influence of two strong neighbouring channels, being periodically added and dropped...
We demonstrate transmission of 16 WDM channels at 10 Gbit/s with 50 GHz channel spacing over 3 times 80 km NZDSF, with small OSNR penalty, using only a single Raman-pumped dispersion compensating module positioned before the receiver.
