摘要： The present invention is related to the field of microrobotics. In particular, microscale actuators are contemplated that are L-shaped microparticle dimers and configured to self-propel through non-Newtonian viscous fluids in a time-asymmetric cyclic magnetic field, thereby providing an improved therapeutic agent delivery platform. The microscale robots can be used to treat any condition associated with non-Newtonian fluids such as pulmonary conditions including, but not limited to chronic obstructive pulmonary disease, cystic fibrosis and/or viral infections.

摘要： The invention relates to an optical system for opto-optical information processing, which can be used in the field of integrated optics, especially for light-controlled switching, branching light and regenerating optical signals in communications networks. The aim of the invention is to provide a means of processing optical signals simply and flexibly. The inventive optical system uses a waveguide array in which the individual waveguides are coupled evanescently. At least one signal beam of a known wavelength is coupled into the waveguide array at an angle which prevents the signal beam from being diffracted when passing through said waveguide array, with at least one control beam of a known wavelength. The signal beam and the control beam cross inside the waveguide array, so an influence can be exerted.

摘要： The present invention is related to a method to control the nucleation and to achieve designed domain inversion in single-domain ferroelectric substrates (e.g. MgO doped LiNbO 3 substrates). It includes the first poling of the substrate with defined electrode patterns based on the corona discharge method to form shallow domain inversion (i.e. nucleation) under the electrode patterns, and is followed by the second crystal poling based on the electrostatic method to realize deep uniform domain inversion. Another objective of the present invention is to provide methods to achieve broadband light sources using a nonlinear crystal with a periodically domain inverted structure.

摘要： The instability of the mean wavelength of a superfluorescent fiber source (SFS) is reduced by randomizing the polarization of light from a pump source or by using polarization maintaining components. In one embodiment, the polarization of a pump source is made more random, leading to greater stability of the mean wavelength of the SFS, with an output mean wavelength that is stable to better than 3 ppm for full rotation of the pump polarization state. In another embodiment, the polarization of optical radiation throughout the device is kept substantially constant by using polarization maintaining fiber and components, thereby leading to enhanced mean wavelength stability of the SFS.
