Acousto-optic interactions involving propagating phonons can break the time-reversal and frequency-modulation symmetry of light. However, conventional acousto-optic modulators based on bulk materials have frequency bandwidth limited to hundreds megahertz due their large structural sizes. Here, we experimentally demonstrate gigahertz single-sideband modulation an etchless lithium niobate integra...

It is well known that having 3 temporal phase shifting (PS) interferograms we do not have many possibilities of using an algorithm with a desired frequency spectrum, detuning, and harmonic robustness. This imposes severe restrictions on the possibilities to demodulate such set of temporal interferograms. It would be nice to apply for example a 7 step PS algorithm to these 3 images in order to h...

Overview Colearning in the expert setting is explored by examining the problem setting and running experiments. Implementations of a variety of existing algorithms from the static and shifting experts framework of Bousquet and Warmuth [2], an adaptation developed by Abernethy, Bartlett and Rakhlin [6] designed to mix weights over tasks, and an ad-hoc task frequency based mixing algorithm are us...
