Evolution of light‐current characteristic shape in high‐power semiconductor quantum well lasers

A Comparison of Amplitude-Phase Coupling and Linewidth Enhancement in Semiconductor Quantum- Well and Bulk Lasers

The amplitude-phase coupling factor a (linewidth enhancement factor) is compared in typical semiconductor quantum-well and bulk double heterostructure lasers. As a direct consequence of the reduction of the differential gain, there is no reduction of a in the single quantum-well lasers compared to the bulk lasers. The number of quantum wells strongly affects the amplitude-phase coupling in quan...

Electron transport in AlGaInP quantum well lasers

Energy storage in quantum-well lasers.

A new scheme of energy storage in single-quantum-well semiconductor lasers is analyzed. This scheme involves the storage of the majority of injected carriers in the continuum states of the surrounding bulk material, in which the carrier density is diluted and the higher-order carrier-density-dependent recombination processes are much smaller. This allows the inversion level to build up to a muc...
