The design of the circuit can be used to create a traffic light wherein twenty open collector that turns ON one at a time in a continuous sequential manner. The 74LSxx family of TTL integrated logic ...

This light activated remote switch circuit could be operated using a flashlight beam and could eb used for toggling a specified load from a distance using an external light source such as a flashlight ...

Optical waveguides are structures that guide and confine light within a small cross-sectional area. In nanophotonic circuits, waveguides are typically fabricated using high-refractive-index materials ...

Redefining the repeating pattern in photonic crystals creates tightly confined pathways for light while preserving symmetry, offering a simple route to ultracompact and low loss light circuits.
