    Abstract: A semiconductor laser device has an active layer, a first cladding layer formed on the active layer, and a second cladding layer formed on the first cladding layer. The first cladding layer is doped with magnesium as a first impurity to have a high resistivity. The second cladding layer is doped with zinc as a second impurity to have a resistivity lower than the resistivity of the first cladding layer.

    Abstract: An optoelectronic device having one or more DBR mirrors having a low voltage drop across the mirror layers and a high reflectivity for emission at a nominal wavelength of 1300 nm below, at and above room temperature. The low resistance DBR may be used as a top output mirror of a tunnel junction VCSEL that reduces resistance and optical losses by reducing the amount of p-type material within the device.

    Abstract: A semiconductor optical device with improved optical gain and enhanced switching characteristics. The semiconductor optical device includes positive and negative electrodes for providing holes and electrons, respectively. The semiconductor optical device also includes an active layer between the positive and negative electrodes. The active layer includes a multiple quantum well structure having p-type quantum well layers and barrier layers. The quantum well layers are doped with an impurity that diffuses less than zinc so that trapping holes are produced and excessive electrons contributing no light emission are quenched by the trapping holes. The impurity can be beryllium, magnesium, or carbon.

    Abstract: A semiconductor laser, optical module using a semiconductor laser, and optical communication system using a semiconductor laser. The semiconductor laser has an active layer between two semiconductor layers and different conduction types and current block layers surrounding the active layer. One of the semiconductor layers has a first growth layer and a second growth layer formed on the first growth layer by a re-growth process after a growth process for the first growth layer. The doping concentration of the first growth layer, in the region of the interface with the second growth layer, is in the range of between 1.5 to 5 times the doping concentration of the second growth layer.
