TL;DR: In this article, the authors present detailed investigations on a device, which utilizes a semiconductor laser amplifier in a loop mirror configuration (SLALOM), and different modes of operation are reported like nonlinear single pulse switching and two-pulse switching at different operation speeds (1-100 Gb/s).

TL;DR: In this article, a review of ultra-high-speed data transmission in optical fibers based on optical time division multiplexing (OTDM) transmission technology is presented, where optical signal processing in the transmitter and receiver as well as the requirements on ultrahigh speed data transmission over a fiber link are discussed.

TL;DR: In this paper, four-wave mixing based on ultrafast nonlinear gain dynamics in a semiconductor laser amplifier was applied for wavelength conversion of a 10-channel OFDM signal with a channel spacing of 9 GHz and a modulation rate of 140 Mb/s per channel.

TL;DR: In this article, a new method of optical frequency conversion was described and demonstrated by a 140 Mbit/s DPSK optical transmission experiment with a fibre-to-fibre efficiency of −10dB.

TL;DR: In this paper, three interferometric all-optical switches based on cross-phase modulation (XPM) in SOAs, the semiconductor laser amplifier in a loop mirror (SLALOM) switch, and the ultrafast nonlinear interferometer (UNI) switch are compared and their application is discussed as demultiplexer in optical time division multiplexing (OTDM) systems for data rates of 40, 80, and 160 Gb/s.
