AI Thread Summary
Infrared photons have difficulty entering nanotubes due to their size being much smaller than the wavelength of infrared light. The discussion compares this to sound waves in a guitar, suggesting that while sound waves can pass through small openings, the behavior of photons is more complex. Near-field effects can excite plasmons in carbon nanotubes with specific infrared wavelengths, but the nature of photon localization remains uncertain. The conversation also touches on the classical treatment of light and its behavior in confined spaces, indicating that photons do not have a position observable like electrons. Overall, the interaction of infrared photons with nanotubes presents intriguing challenges in photonics.

Can a medium range infrared photon enter a nonotube
 
Physics news on Phys.org
A typical nanotube has a diameter much smaller than the wavelength of visible or infrared light, so I don't think that there can be a situation that can be described as such a photon being confined inside the tube. Anyone correct me if I'm wrong.
 
What about a gutar the sound wave is much larger than the diameter of the hole in the sound box yet the air particles are smaller. Is it not the same for a photon
 
I found this on the internet "In this work, we further develop this idea by shaping the wavefront of the infrared light (at a wavelength of 1064 nm) passing through a 180-nm-radius hole that is surrounded by well-designed groove patterns into predesignated complex patterns such as Latin letters"
 
See:

In the near field, plasmons in CNTs can be excited by infrared light (excitation wavelength 6-10μm). I don't know if this counts. Photonics isn't really my area.

Where on the internet did you find this?

Does a photon even have a position observable in the way how an electron has one? It's possible to create an electron wavepacket that is localized inside some boundaries, but that kind of a wavepacket can't have a single de Broglie wavelength. With the quanta of the electromagnetic field, the situation is even more difficult.

No, but I think the quote in post 4 is treating light (semi-)classically. Without a reference, I can't say for sure, but I do know that light does funky things in the near field limit.

I was thinking as the sound wave gets destorted as it moves thru the hole in the gutar, mabe the electromagintic field of the photon gets simalarly destorted
