Problem 3 (25 points) A silicon photodetector has an internal photo responsivity of 0.5 A/Wt wavelength of 850 nm. When photons of wavelength 850 nm are incident normally on this photodetector, some photons are reflected back and some photons penetrate to the detection region and are absorbed by the photodetector. (a) The index of refraction of silicon is 3.45. If the electric current measured by this photodetector is 20 mA, what is the incident optical power? (b) Silicon has a...

A small laser emits light at power 3.11 mW and wavelength 486 nm. The laser beam is focused (narrowed) until its diameter matches the 1236 nm diameter of a sphere placed in its path. The sphere is perfectly absorbing and has density 3.00×103kg/m3. What is the beam intensity at the sphere's location? Tries 0/10 Calculate the radiation pressure on the sphere. Tries 0/10 Calculate the magnitude of the corresponding force. Tries 0/10 Calculate the magnitude of the acceleration that force...
