comment Probability to create an electron - hole pair inside Si
@boyfarrell I did as you suggested, I would have thought the statement that " ... alpha is a strong function of wavelength" and the subsequent curve would have been a clue ... But if it helps I changed it. Thanks for the suggestion.

comment Probability to create an electron - hole pair inside Si
This is not wrong. Let me explain. The energy of the photon is the selected by the wavelength. The photon moving through the Si leaves a a probability trail of e/h pairs with a characteristic depth that \$ e^{-1} \$ absorption. That formulate above is a probability. To check this out look at "Donati, Silvano". "Photodetectors: Devices, Circuits and Applications". Prentice Hall PTR, 1999. The graph above is from internal data that I've collected and verified. Do a little research.

Oh boy ... I am assuming the external QE ** is one. i.e. every photon **once ** it is the Si is subject to the probability of absorption as defined above. Since no external conditions are noted one simply needs to apply this to the photons that **do make it into the Si.

Oops! Sorry the above comment should read "doesn't" NOT "does". Fat fingers.

I'll give you a hint. It does matter which mirror is misaligned.

comment Is emission/absorption of a photon lossy?
Or if the material is rough (think of powdered glass) then the photon energy will go purely into heat.
