    • On a first region that is a part of one main face of a semiconductor substrate 1, a first semiconductor laser structure 10 is formed so as to have a first lower cladding layer 3, a first active layer 4 with a first quantum well structure and first upper cladding layers 5, 7, which are layered in this order from the semiconductor substrate side, thereby forming a first resonator. On a second region that is different from the first region, a second semiconductor laser structure 20 is formed so as to have a second lower cladding layer 13, a second active layer 14 with a second quantum well structure and a second upper cladding layer 15, 17, which are layered in this order, thereby forming a second resonator. End face coating films 31, 32 are formed on facets of the first and the second resonators, and a nitrogen-containing layer 30 is formed between the facets of the first and the second resonators and the facet coating film. In the semiconductor laser device provided with a high-output dual-wavelength lasers that are formed monolithically, the decrease of the COD level during the high-output operation of the laser can be suppressed.

    • The invention relates to the design, fabrication, and use of semiconductor devices that employ deep-level transitions (i.e., deep-level-to-conduction-band, deep-level-to-valence-band, or deep-level-to-deep-level) to achieve useful results. A principal aspect of the invention involves devices in which electrical transport occurs through a band of deep-level states and just the conduction band (or through a deep-level band and just the valence band), but where significant current does not flow through all three bands. This means that the deep-state is not acting as a nonradiative trap, but rather as an energy band through which transport takes place. Advantageously, the deep-level energy-band may facilitate a radiative transition, acting as either the upper or lower state of an optical transition.

    • A broad area semiconductor laser device is provided having an NFP with top hat shaped profiles for the P wave and the S wave, which result from polarized beam splitting of the emitted light. The broad area semiconductor laser device of the present invention has the same structure as the broad area semiconductor laser device of the prior art, except that the composition of an etch stop layer is different. The semiconductor laser device includes an n-Al0.5Ga0.5As first clad layer, an active layer including an AlGaAs optical guide layer and an AlGaAs quantum well layer, a 0.3 μm thick p-Al0.5G0.5As lower second clad layer, an Al0.7Ga0.3As etch stop layer, a p-Al0.5Ga0.5As upper second clad layer, and a p-GaAs contact layer, which form a laminated structure on top of an n-GaAs substrate.

    • Semiconductor laser diodes, particularly high power AlGaAs-based ridge-waveguide laser diodes, are often used in opto-electronics as so-called pump laser diodes for fiber amplifiers in optical communication lines. To provide the desired high power output and stability of such a laser diode and avoid degradation during use, the present invention concerns an improved design of such a device, the improvement in particular significantly minimizing or avoiding (front) end section degradation of such a laser diode and significantly increasing long-term stability compared to prior art designs. This is achieved by establishing one or two nullunpumped end sectionsnull of the laser diode. One preferred way of providing such an unpumped end section at one of the laser facets (10, 12) is to insert an isolation layer (11, 13) of predetermined position, size, and shape between the laser diode's semiconductor material and the usually existing metallization (6).
    • 半导体激光二极管,特别是大功率AlGaAs基脊波导激光二极管,通常用作光电子学中所谓的用于光通信线路中的光纤放大器的泵激光二极管。 为了提供这种激光二极管的期望的高功率输出和稳定性并且避免在使用期间的劣化,本发明涉及这种器件的改进的设计,特别地显着地最小化或避免了这种激光(前端)部分退化的改进 二极管,并且与现有技术设计相比显着提高了长期稳定性。 这是通过建立激光二极管的一个或两个“未使用的端部”来实现的。 在激光刻面(10,12)中的一个上提供这种未卷边端部的一种优选方式是将预定位置,尺寸和形状的隔离层(11,13)插入激光二极管的半导体材料和通常存在的 金属化(6)。
