Abstract
In general, this disclosure describes various optical ultrasound transducers and methods of producing such. As one example, an optical ultrasound transducer comprises an optical fiber and a polymer layer formed on the optical fiber to receive light from the optical fiber. The polymer layer may absorb light of a first wavelength and be substantially transparent to light of a second wavelength. In response to the light of the first wavelength, the polymer layer may generate an acoustic tone. The optical ultrasound transducer may further include an optical detector formed on the polymer layer, the optical detector comprising an etalon structure having a first mirror layer and a second mirror layer separated by a compressible layer, wherein the compressible layer resonates in response to the light of the second wavelength passing through the polymer layer and is compressible in response to acoustic pressure from echoes of the acoustic tone.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
