Organic LEDs articles from across Nature Portfolio Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element.

This paper presents an analysis of long term-memory effects on power measurements with diode power probes. We show that a power probe calibrated with a single-tone sinusoidal excitation can provide ...

Conventional AlGaAs laser diodes with uniform thickness active layers of various cavity lengths are investigated. It is recognized that the extension of the cavity length is effective in the ...
