We demonstrate large bandwidth (0.5 GHz) range correlation in a spectral-spatial holographic (SSH) material under practical conditions. Adaptation of this work to a range Doppler correlator over the same bandwidth is a prospect of future work.

The problem of creating optical parametric amplifiers of femtosecond pulses up to the multiterawatt level was fiist discussed in [l, 21. In these papers, as well as in subsequent studies [3-91, only nonlinear elements made from KDP crystals, whose aperture can be as great as 30cm, were considered as nonlinear elements for final cascades of optical parametric amplifiers (OPAs). The most promising pump source is the second harmonic of a Nd:glass laser with a wavelength of 3L3=527nm. At this pumping, the KDP crystal has two serious disadvantages: it absorbs greatly at wavelengths higher than 1200nm and has maximal gain bandwidth (1000-1200~m~[l~]) at the wavelength of signal 1050-1 1 OOnm, i.e., at degenerated (or nearly degenerated) phasematching. In this wavelength range, however, it is difficult to create light sources with pulse duration of less than 50fs.

Counter propagation between data and clock pulses inside the optically controlled EAM is used for all-optical timing extraction and demultiplexing. Demultiplexing from 4OGbit/s showed error free operation with I 200 fs jitter for the recovered clock.

We have demonstrated optical single sideband (OSSB) transmission with standard fibre Bragg grating (FBG). No RF analog circuit is necessary. FBG not only suppress the sideband but also can compensate for chromatic dispersion of the link. The higher data rate is, the better SBSR will be. Therefore, this technique will be ideal for OC768 and beyond. The FBG in our experiment is the as first prototype. We are working on a next-generation design that has even sharper transition and straight group delay response.

We demonstrate single-shot kHz SPIDER measurements of 3 cycle laser pulses from a gas-filled hollow fiber with subsequent compression. A remarkably low mean shot to shot pulse duration variation (21 as) is seen from these pulses.

We demonstrate a tunable WDM wavelength converter based on XPM in just 6 m of highly nonlinear holey fiber and incorporating a precise, compression tuned apodized fiber-grating filter. We achieve broadband 10 Gbit/s wavelength conversion (/spl sim/20 nm) with a constant pulsewidth due to short device length and correspondingly reduced pulse walk-off effects.

We report the development of an ultralow-threshold modelocked Ti:Al/sub 2/O/sub 3/ laser. Since the pulse energy of a laser is given by its average power divided by its repetition rate, increasing the cavity length produces an increase in pulse energy. This increased pulse energy enables high performance KLM operation at low powers while also decreasing the spot size of the laser mode to reduce pump thresholds. We report what is, to our knowledge, the lowest threshold achieved to date for a Kerr lens mode locked Ti:Al/sub 2/O/sub 3/ laser.
