The Interaction of Sound and Light - Comments

AI Thread Summary
The discussion highlights the intriguing interactions between sound and light, particularly in the context of acousto-optic devices, where TeO2 is preferred over quartz. Participants express appreciation for the insights shared in the original post and reference complex literature on the subject. A playful poem about the relationship between photons and phonons adds a light-hearted touch to the conversation. There is also a question raised regarding the incomplete understanding of the physics behind sonoluminescence. Overall, the thread emphasizes the fascinating and complex nature of sound-light interactions.

Very interesting! I had no idea about most of those interactions between light and sound!
 
Nice Insight Alex!
 
A minor point: in acousto-optic modulators/scanners/deflectors, TeO2 is more commonly used rather than quartz. Some good references for this (highly complex) subject are Korpel "Acousto-Optics" , Goutzoulis "Design and Fabrication of Acousto-Optic Devices" and a fine chapter in Saleh and Teich "Fundamentals of Photonics".
 
Code: 
A photon out cruising at night,
saw a phonon just off to his right.
Said the P to the P,
is it better to be,
a sound instead of a light.

That was a fun insight. Thanks for sharing your knowledge.

Is it true that the physics of sonoluminescence is not fully understood yet?

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
