Soap films that are very thin compared to the wavelengths of light moving through them reflect no light at all, making them invisible. You see this at the top of the soap film in the Soap Film on a ...

In this work, we investigate LIC growth on dielectric oxide thin films in air environment irradiated by MHz sub-ps laser at 515 nm. The experiments were performed in similar conditions as in the work ...

Understanding structure and polymorphism is relevant for any organic device optimization, and it is of particular relevance in 7-decyl-2-phenyl[1]benzothieno[3,2-b][1]benzothiophene (Ph-BTBT-10) since ...

A method for measuring optical thickness changes in a thin film using a single laser beam is proposed and demonstrated. Theory suggests that when a half plane phase shift is applied to a Gaussian ...

For instance, SPR substrates need to be coated with an expensive gold film (Hobbs et al., 2016), whose thickness has to be precisely controlled at the nm level. Recently, phase-sensitive ...

Visualizing and measuring thin-film thickness at the nanoscale during dynamic evolution has been an open challenge for long term. Here, a joint-imaging method and the thereof innovative procedure are ...

It's so thin that there is no noticeable path length difference between the light reflected from the front and back of the soap film. However, there is still a phase shift from the reflection off ...

Remember, when a wave is in phase with another wave, their crests and troughs are amplified, meaning that the light is brighter, thanks to constructive interference. And when a wave is out of ...

Taking thin films to the extreme Date: September 30, 2014 Source: American Institute of Physics (AIP) Summary: Applying a well-known optical phenomenon called thin-film interference, a group of ...
