"Do you remember what I just said? It has similar properties to semiconductors."

"The rectification effect of semiconductors is also reflected in it."

"As we all know, the conductivity of a semiconductor is related to the direction of the applied electric field. If a positive voltage is applied across its terminals, current can flow smoothly, but if a reverse voltage is applied, it will not conduct electricity."

"This semi-permeable material is similar, except that voltage is replaced by light pressure and electrons are replaced by photons."

Mo Zeyang's breathing gradually became rapid.

"This, this is a perfect electronic switch!"

"This characteristic alone can easily solve the logic gate problem of photonic computers!"

Lu Yongchang corrected softly, "To be precise, it's a photon switch."

In the simplest terms, logic gates are 0 and 1.

In electronic computers, the rectification effect of semiconductors can be used to make "electronic switches" for counting 0s and 1s, which is the basis of electronic computers and binary code.

With 0 and 1, a series of logical operations are possible.

The technology is very basic, but for photonic computers, it is the biggest challenge.

Humans began researching this technology over a century ago.

Of course, some solutions were also found.

For example, a surface wave excitation source can be fabricated on the surface of a gold film, and the path of light can be controlled by using trenches.

By utilizing the different phase differences formed by the convergence of light emitted from multiple light sources after passing through different path lengths, a series of logic gates were obtained.

At the time, the experiment was very successful.

Compared to circuit logic, the logic operations of optical logic gates are incredibly fast!
