Transmittance of one material through a multilayer
Good morning,
I have the transmittance and the reflectance spectrum of PET (Polyethylene terephthalate) and I also have the transmittance and the reflectance spectrum of PET + Copper (50 nm). I would ...

Phase shifted Optical Fiber Bragg grating Response
As we know there is a narrow notch in the reflectance spectrum of a Phase shifted FBG. We have Bragg condition for reflected band of any uniform FBG. My question is that, does anyone know any relation ...

Coupling of resonant modes in a 1D Photonic Crystal
In 1D Photonic crystals, a defect can be introduced to create a defect/resonance mode and enable transmission. At first considerations, the thickness of the single defect layer determines the ...

How thin can a layer be in a multilayer and still act as a reflection interface?
Assume a multilayer with high and low refractive index layers. Now imagine that the high refractive index layers are successively made thinner and thinner. At what point would a single layer no longer ...

A simple thin-film transmittance calculation problem
I am trying to reproduce results of thin-film transmittance given in this article by using this online thin-film calculator tool (www.filmetrics.com). I would like to use the calculator later for more ...
