We describe a technique for the measurement of optical gain and loss in semiconductor lasers using a single, multisection device. The method provides a complete description of the gain spectrum in absolute units and over a wide current range. Compari

In this paper we summarize recent developments in the experimental study of the intrinsic gain and recombination characteristics of GaInP quantum wells. Derivation of gain spectra from spontaneous emission spectra observed through a top-contact windo

The cause of the unusual spectral distribution, often observed in InGaAs/GaAs quantum-dot lasers, is investigated by analyzing the spectra from devices fabricated with different substrate thickness (100–400 μm). Using a Fourier transform analysis

GaAs‐AlGaAs multiple quantum well (MQW) injection lasers with well widths from 55 to 13 A have been grown by molecular beam epitaxy and operated at room temperature, showing emission at wavelengths down to 704 nm, the shortest reported for a MQW in

We have recorded spontaneous emission spectra from multiple quantum well lasers grown by molecular beam epitaxy with 25‐A‐wide GaAs wells by opening a window in the top contact stripe. These spectra have a low‐energy tail and consequently the g

We investigate the electroluminescence spectra of edge-emitting lasers having self-assembled quantum dots as the active medium. A broad laser emission is observed with a modulation of intensity corresponding to single or bunches (supermodes) of Fabry
