| 英文摘要 | Vertical-cavity surface-emitting laser (VCSEL) structures are described which enable their use as widely wavelength-swept coherent light sources and multiple-wavelength VCSEL arrays. Three general configurations are described: (a) a semiconductor-cavity-dominant (SCD) with high reflection at the semiconductor-air interface, (b) an extended-cavity (EC) design in which reflections at the semiconductor-air interface is reduced to insignificance compared to the SCD design with a refractive index-matched layer (i.e., AR layer) so the entire structure resonates as one cavity, and (c) an air-cavity-dominant (ACD) design which facilitates a larger field confinement in the air gap, and the increased field confinement causes the air gap to be the dominant cavity. |
