Diffraction Of Light

The diffraction of light by surface waves on transmission through the propagation surface was investigated and a suitable Raman Nath parameter defined. Asymmetries in the intensities of the ± 1 diffraction orders were predicted, shown to be much larger than for the equivalent bulk wave case, and were verified experimentally for light incident on 96 and 480 MHz surface waves on y–z lithium niobate. Also analyzed theoretically are the diffraction of light by Blaustein–Gulyaev waves and the intensities of the ± 2 orders for transmission diffraction of light by surface waves.

High-frequency surface acoustic waves (SAW) were generated and transmitted along single-crystal lithium niobate (LiNbO3). The standing surface waves (SSAW) formed between two parallel inter-digital transducers (IDTs) on a LiNbO3 substrate, were employed to drive the micro-drop mixer. An SSAW device was designed, micro-machined and tested. When an AC signal with the frequency of 61.4MHz was applied to the IDTs, vortex appeared in the drop consisted of two incompatible liquid (ink and glycerol). The evolution of the vortex was recorded in this work. With the evolution of the vortex, mixing process of two incompatible liquid has been demonstrated. The mixer is of significant relevance for many bio-technological applications and in particular for lab-on-chip. While the experimental liquids were mutually incompatible, the ink could only be divided into smaller drops.
