We have studied the lateral waveguiding properties of gain-guided and index-guided II–VI lasers under pulsed conditions and their influence on threshold current density J th and differential quantum efficiency η. Thermal index-guiding was found to

We have used a combination of techniques to characterize low defect density (≤ 10 5 cm −2 ) blue-green separate confinement heterostructure lasers. The limits of lattice mismatch between the substrate and quaternary cladding layers that result in

Three distinct etch pit features in ZnSe based epitaxial layers have been identified. The features were observed with optical dark field microscopy and confirmed to be pits using scanning electron microscopy. Using transmission electron microscopy, w

Carrier confinement in blue‐green II–VI semiconductor lasers was investigated. For devices longer than 300 μm an energy barrier of 260–280 meV was found to confine the electrons, the carrier being mainly responsible for leakage, within the act

In-Plane Semiconductor Lasers: from Ultraviolet to Midinfrared.
We have demonstrated the feasibility of reading a high density Digital Versatile Disc using a green ZnSe based laser as the light source. In order to achieve this, high quality optical and electrical properties are required from the laser. We fabrica
