T9
Purpose
This sample as two sets of 6 transducers. Each set is comprised of three transducers toward the edge and three transducers away from the edge. One set is pointing away from each other (Set 1), while the other points towards each other (Set 2). These are designed to see the interactions of SAW waves with two transducers in the light path.
Past:
Y-cut Lithium Niobate. Normal prep, no proton exchange.
Only minor flaws in the transducers are visible.
Sign
Set 1 (pointing away from each other)
Near the edge
Away from the edge
Set 2 (pointing towards each other)
Near the edge
Away from the edge
Wire Bonded as follows:
Smith and SWR charts before impedance matching. It is noted that very few of the transducers are functioning. Specifically only T4,T6,T7,T8, and T10. Unsure as to why.
