An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

The VSMY98545 features a 42 mil by 42 mil emitter chip, which supports a low thermal resistance of 10 K/W junction-to-pin, and enables high drive currents up to 1 A and pulses up to 5 A. The emitter’s ...

For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a ...
