What makes SiO2 an excellent cladding material for optical fibers?

AI Thread Summary
SiO2, or silicon dioxide, is recognized as an excellent cladding material for optical fibers due to its low refractive index, which enhances light transmission. Unlike germanium oxide, SiO2 is not water-soluble, making it more stable and durable for fiber applications. Its properties contribute to efficient light guiding and minimal signal loss in optical fibers. The discussion emphasizes the importance of SiO2's characteristics in fiber optics technology. Understanding these properties is crucial for advancements in optical communication systems.

can anyone please explain this property of silicon:
An excellent oxide as the low-refractive-index cladding material.
thanks

That wouldn't be a property of silicon but presumably it's native oxide, SiO2. It's an excellent oxide because it isn't water soluble as germanium oxide (GeO2).

SiO2's low refractive index means it is used to build optical fibers. You can find out a lot about this on Wikipedia.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
