Signal amplified by pumping non-linear element
Brief Description:
Develop an ultra low-noise parametric amplifier.
Develop an ultra low-noise parametric amplifier.
Approach:
Use interdigitated electrodes connected to an antenna to convert electromagnetic radiation to a surface acoustic wave on a piezoelectric lithium niobate substrate. Drive a pump signal into a non-linear element on the surface to amplify the signal. Collect the amplified signal at a second set of interdigitated electrodes.
