Depletion Layer Width in Fiber Optic Transmission Formulas

The depletion Layer Width is the distance across the region near the p-n junction where mobile charge carriers (electrons and holes) have been significantly depleted or removed. And is denoted by w. Depletion Layer Width is usually measured using the Meter for Length. Note that the value of Depletion Layer Width is always positive.

FAQ

What is the Depletion Layer Width?

The depletion Layer Width is the distance across the region near the p-n junction where mobile charge carriers (electrons and holes) have been significantly depleted or removed. Depletion Layer Width is usually measured using the Meter for Length. Note that the value of Depletion Layer Width is always positive.

Can the Depletion Layer Width be negative?

No, the Depletion Layer Width, measured in Length cannot be negative.

What unit is used to measure Depletion Layer Width?

Depletion Layer Width is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Depletion Layer Width can be measured.
