Substrate Design
the cells are grown on a transducer substrate similar to those described here. The optimization of the transducer layer is different in this case. Here we are much more concerned with optimizing the optical properties of the transducers. The goal is to reduce the amount of blue light reaching the cell and either maximize the reflected or transmitted light, depending on the experiment requirements. We still have to take care that the acoustic performance of the transducer is good and that the acoustic bandwidth is sufficient to generate waves at the Brillouin frequency.
