This Design Idea describes a method by which you can detect and assess air or liquid fluid flow using an externally heated semiconductor diode. Airflow across the heated diode reduces its temperature, ...

Rarely a week goes by that some company doesn’t offer to send us their latest and greatest laser. You know the type — couple of aluminum extrusions, Class 4 diode flopping around in the breeze, and no ...

P-n diodes are two-terminal devices that consist of two types of semiconductor materials (i.e., a p-type and an n-type ...

Teleportation of optical qubits can enable reliable logic operations in massively parallel quantum computers, as well as the formation of secure quantum networks. Photon teleportation has previously ...

Our expert, award-winning staff selects the products we cover and rigorously researches and tests our top picks. If you buy through our links, we may get a commission. James has been writing about ...

The development of power diode pump laser sources that demonstrate extended life and higher brightness have resulted in this novel technology becoming commercially feasible. This effect prevents ...

Think about how easily you recognize a friend in a dimly lit room. Your eyes capture light, while your brain filters out ...
