Calculate the thickness of the active region of a photodiode

Reference no: EM131018989

The detectors used in optical fiber networks operating at 850 nm are usually made of silicon, which has an absorption coefficient of 1.3 × 105 m-1 at this wavelength. The detectors have coating on the front face that make the reflectivity at the design wavelength negligibly small. Calculate the thickness of the active region of a photodiode designed to absorb 90% of the light.
