摘要： Some embodiments may include a power monitor to measure power of laser light propagating in a core of an optical fiber; the power monitor to generate a sensor signal using an optical sensor having a light sensitive section with no line of sight to part of the optical fiber; wherein the sensor signal is derived from light emerging laterally from the part of the optical fiber. Other embodiments may be disclosed and/or claimed.
