Electroluminescence (EL) testing of Light Emitting Diode (LED) structures is usually done at the chip level. Assessing the optical and electrical properties of LED structures at the wafer scale prior to their processing would improve the cost effecti

An optimization of channeled substrate narrow stripe GaAs/GaAlAs lasers for operation in the zero‐order transverse mode to output powers of 10 mW is described. A correlation between zero‐order mode power and substrate‐induced optical loss is de

A study has been made of the susceptibility of 20‐μm oxide stripe GaAlAs lasers to current transients. The current amplitude (as a function of duration) required to cause increased threshold currents or degradation rates has been found. Damage cau

A narrow stripe (GaAl) As/GaAs laser is described, which has low source noise, high linearity and an expected life in excess of 20,000 hours. It has a short coherence length compared with a self-focused or refractive index guided laser giving very go

Measurements have been made of the frequency modulation parameter for a number of distributed feedback lasers at various frequencies and output levels. The results are interpreted in terms of a computer model for DFB lasers and the influence of lasin

Optical communications systems increasingly need to make use of single longitudinal mode (SLM) lasers so that fibre dispersion does not degrade system performance. At gigabaud rates over long distances with conventional Fabry Perot lasers dispersion

We report the generation of picosecond pulses with oxide‐isolated‐stripe, double heterostructure GaAlAs laser diodes of varying lengths. A pulse width of 15 ps at a repetition frequency of 1 GHz is achieved with a 60‐μm‐long device. The expe
