We report on the measurement of the optical absorption of bulk crystalline silicon at 1550 nm. Using the photodeflection technique, absorption as low as 5 ppm / cm has been measured on a sample with a resistivity of 10 k Ω · cm . The absorption as a function of the resistivity has been derived for n-type silicon. graphing quadratic equations in standard form
