This optocoupler is made of LEDs connected to CTS, which transmit signals in the form of lights to the photoresistors, which connected to the series form AND logic gates.

In this case we have 6 outputs at 4 inputs.

Light Emmiting Transistors (LETs), using CTS 4.3 in this case, can serve as a optocoupler, a

display-pixel matrix, a light decoder, etc.

The specific polarization of the lines, or the inputs can independently turn on or off any single LET.


Next video shows how the polarisation of sub-addresses works.

Another example of optocoupler or light decoder using LEDs and phototransistors.

In this example an active optocoupler address on the left will send a signal to CTS, and encoder.

A signal will be multiplexed to the decoder or similar device and then transmited to another optocoupler address of CTS on the right.

This shows the possibility of use CTS in telecomunications which makes whole system easyer to build and controll, and with less built-in components.

Even more output addresses can be built with light based telecommunication systems.

This CTS have fractal structure.

Every address will have light based logical filters or gates wich will allow just one or multiple specific lights (red, green, blue, yellow,...) to pass.

To be active, the address must have all input light-lines active, and must have specific


When some of addresess input light-lines are not active the adress will be inactive.

Also, the address remain inactive when lights-combination does not correspond to the logical filters of the specific address.

By every next level of addresses we will lose one of "key" or "door opener" light color.

This specific "key" color is similar or analogous to so called "enable" function of decoder.
