In your original post, complete the following:
Share  an engineering (or other) application of an infinite series.  Identify  it in math notation, an image of a graph, or in a clear explanation in the context  of the application.  You do not need to explain the entire topic, only  identify the infinite series within this application, and tell us some  of what it helps to accomplish here.  While the type of series  expansion you discuss will likely be the same as some of your  classmates, the application example you present should be unique.

  “Laser diodes can create lasting conditions when pumped with electrical curren

 
“Laser diodes can create lasting conditions when pumped with electrical current at the diode junctions.”
What “lasting conditions” are you referring to?  What is “pumped” electrical current?
 
Here is an example of operational details explained at the technical level I am expecting from engineering students:
Laser diodes have an intrinsic  (un-doped silicon or germanium) layer sandwiched in between the P and N  doped regions.  The boundaries between the intrinsic region and the P  and N regions are reflective like a mirror.  
When the electrons and holes  recombine in the intrinsic region during forward current through the  diode, the energy lost by that recombination is emitted in the form of a  photon.  These photons collide with other incoming electrons, which  produces even more photons.  Each emitted photon bounces back and forth  between the two reflective boundaries, which concentrates and guides  them until they emerge as coherent light.  A lens further focuses the  beam.

 Transistor biasing is critical in an amplifier to make sure that the  transisto

 Transistor biasing is critical in an amplifier to make sure that the  transistor operates in a stable state without distortion of the signal.   Different bias configurations are used for different applications  depending on how you want the amplifier to operate.  One of the easiest  to implement is base biasing, what are some of the issues with base  biasing?  
answer the following:
Why is emitter bias more stable than base bias?
Explain why the base bias Q-point changes with temperature.
How does emitter-feedback bias improve on base bias?

  1. Light emission – a Light-emitting diode is something that we are  very fami

 
1. Light emission – a Light-emitting diode is something that we are  very familiar with, more commonly referred to as an “LED.” LED’s are  used in many applications and are becoming more and more popular due to  their efficiency and longevity. “A typical LED for lighting can deliver  50–60 lumens per watt, which is approximately five times greater  efficiency than a standard incandescent bulb (Thomas L Floyd).” When the  LED is in forward bias, electrons that combine with holes in p-type  materials coming from the n-type materials. Once recombination takes  place an energy is released in the form of photons. A semiconductive  material is what allows the photons to be projected as visible light.
2. A phototransistor is similar to a Bipolar Junction Transistor  (BJT) except the base currents are generated from two different sources.  The base current in a BJT is produced by a voltage source while the  phototransistors come from a light source. Phototransistors can be found  in punch card readers, counting systems, and even in light  controlling/detection systems. The phototransistor operates dependent on  the level of radiation detected in form of light, and not just any  light source but only those within a certain range of wavelengths.
