A photodiode receives 1 µW of 850 nm light. Calculate the photon flux and shot noise current. Common Error: Using the power in watts without converting wavelength to frequency: ( P = N_photons \cdot h\nu ). Unpatched solutions often use ( h\nu = 1240 \text eV·nm / 850 \text nm ) but incorrectly convert eV to Joules. Patched Solution: ( \nu = c/\lambda = 3\times10^8 / 850\times10^-9 = 3.53\times10^14 \text Hz ) ( E_photon = h\nu = (6.626\times10^-34)(3.53\times10^14) = 2.34\times10^-19 \text J ) Photon flux ( \Phi = P/E_photon = 1\times10^-6 / 2.34\times10^-19 = 4.27\times10^12 \text photons/s ) Shot noise ( i_shot = \sqrt2qI_dcB ) (where q is electron charge, I_dc = quantum efficiency * Φ * q, B=bandwidth). The patched version also provides a script for Python/Matlab to simulate noise. Leo was confused
