Optical amplifiers are essential in modern fiber-optic networks, boosting signal strength without electrical conversion. An illustration of the effective gainis given below. Note the presence of a gain peak around 1530nm and a semi-flat gain. Energy-efficient and small enough to fit in a smartphone, an optical amplifier developed at Stanford could improve fiber optic networks and spur new technologies in biosensing, data communications, and more.
[pdf] To date, three main optical switching technologies have been investigated which resulted in increasing data transfer capabilities for the data center networks. Optical Circuit Switching (OCS): OCS has three.

[pdf] Although most people want to make measurement in units of dBm or Watts, an optical power meter is only capable of measuring either the current or the voltage generated by a photodetector. When interfacing with a photodiode, the quantity that must be measured is current. In fiber optics, lasers, sensors, and optical communication links, this measurement is central to confirming that signals are strong enough to perform reliably without overloading. Quantum efficiency is dependent on many factors, but in general if the energy of the photon, E = h v, is greater than the energy gap of the device, these photons will be absorbed very near the surface where the recombination rate is high and will contribute to the photocurrent.
[pdf] Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature.
