A technique to measure low frequency noise in illuminated photodiodes is presented, and some 1/f noise results are given for InGaAs devices. The ability of photodiodes to convert laser noise into RF noise is also discussed, together with other types of 1/f noise arising directly from the optical fiber, and particularly from scattering phenomena inside the fiber.
