A Germanium sample of dimensions 1 cm x 1 cm is illuminated with a 20 mW, 600 nm laser light source as shown in the figure. The illuminated sample surface has a 100 nm of loss-less Silicon dioxide layer that reflects one-fourth of the incident light. From the remaining light, one-third of the power is reflected from the Silicon dioxide-Germanium interface, one-third is absorbed in the Germanium layer, and one-third is transmitted through the other side of the sample. If the absorption coefficient of Germanium at 600 nm is 3 x 104 cm-1 and the bandgap is 0.66 eV, the thickness of the Germanium layer, rounded off to 3 decimal places, is ______ μm.
    Correct answer is between '0.230,0.232'. Can you explain this answer?

    Incident power = 20 mW = Pi
    Reflected power (Pr) from SiO2 is one-fourth, i.e

    Power left will be:

    From this  power, the power reflected from Ge Interface is:

    Now, the power absorbed in the Germanium layer is:

    Power Transmitted through the other side of the sample is:

    The power entering Germanium Sample = Power absorbed + Power Transmitted, i.e.


    α = absorption coefficient
