We report on a novel 18-TW peak power light source delivering pulses with 80-mJ energy and 4.5-fs duration. The system is based on optical parametric synthesizer principle involving multi-color optical parametric chirped pulse amplification stages.
The endeavour of generating shorter and shorter light pulses lead to the optical parametric chirped pulse amplification (OPCPA) technique, which provides considerable broader gain bandwidth corresponding to a pulse duration of one to three optical cycles. Systems with such a short duration and multi-terawatt to petawatt power levels provide a unique tool for attosecond [1] and laser-plasma physics...
We propose a scheme enabling direct serial-to-parallel conversion of OTDM data tributaries onto a WDM grid, based on optical Fourier transformation with spectral compression. Demonstrations on 320 Gbit/s and 640 Gbit/s OTDM data are shown.
High-speed (121/25 ps rise/fall time) and low-switching energy (7.1 and 3.4 fJ) all-optical flip-flop operation of single-wavelength high-mesa asymmetric active-MMI bi-stable laser diodes is demonstrated for the first time using 25 ps long switching pulses.
We report on recent results on Terabit per second single channel systems using a record high 1.28 Tbit/s OTDM data rate. We discuss demultiplexing and optical sampling in several different materials as well as transmission.
We describe methods to generate and optically signal process Tbaud serial optical data signals. We present sub-systems making serial optical Tbit/s systems compatible with standard Ethernet data for data centre applications, and present Tbit/s results using a.o. silicon nanowires.
This paper demonstrates the first transmission of a 1.28 Tbaud data signal. The transmission link is a 50-km dispersion managed fibre consisting of super large area fibre and inverse dispersion fibre. Error-free performance (BER<;10-9) is achieved after transmission.
This work successfully demonstrates SOA-based optical switches that utilize optical filtering techniques at ultrahigh bit rates up to 640 Gbit/s. A simple condition for the minimum bit pattern length is derived and an effective method for simulating patterning effects is introduced. This method is then used to analyse a specific configuration for high-speed signal processing.
We report on the first demonstration of 640 Gbit/s wavelength conversion by FWM. This is demonstrated using a novel elliptic core PM-HNLF giving sufficient FWM conversion bandwidth.
