    • The invention concerns opto-electronic components with multilayer heterostructures, and in particular laser diodes emitting magnetic transverse polarization. One of the technical problems of this type of component is to ensure proper confinement of emission optical modes in the plane of the layers by modulating the effective index, so as to obtain good optical quality of the emission mode. The invention proposes to perform modulation of the effective index of the planar guide mode by coupling it with the surface plasmon obtained by deposition of a metal layer on the component heterostructure, Thus the planar structure of the component is maintained while the desired effective index modulation is obtained. This arrangement is applicable to different types of laser structures, such as, for example, Fabry-Pérot type quantum cascade laser, but also DFB or A-DFB, ARROW type lasers or still photonic crystals. The shape of the metal deposit is simply adapted to each type of structure.
    • 本发明涉及具有多层异质结构的光电子部件,特别是涉及发射磁横向极化的激光二极管。 这种类型的元件的技术问题之一是通过调节有效折射率来确保发射光学模式在层面内的适当限制,从而获得发射模式的良好光学质量。 本发明提出通过将其与通过在成分异质结构上沉积金属层而获得的表面等离子体激元来执行平面引导模式的有效折射率的调制。因此,在期望的有效折射率调制为 获得。 这种布置适用于不同类型的激光器结构,例如法布里 - 珀罗型量子级联激光器,还可以适用于DFB或A-DFB,ARROW型激光器或静止光子晶体。 金属沉积物的形状仅适用于每种类型的结构。
