摘要	It has been discovered that co-doping of Er-doped Si with a light element such as C, N or F can result in substantially increased Er luminescence. A further increase in luminescence can result if, in addition, oxygen is present in the Si. Apparatus or systems according to the invention comprise a device (e.g., laser, optical amplifier, LED) that comprises a planar waveguide whose core region contains, in addition to at least 90 atomic % Si or SiGe alloy, Er, Pr and/or Nd, and further contains C, N and/or F, and preferably also contains oxygen. Currently preferred apparatus or systems according to the invention comprise means for electrically pumping the waveguide means.
其他摘要	已经发现，掺杂Er的Si与诸如C，N或F的轻元素可以导致显着增加的Er发光。如果另外在Si中存在氧，则可以导致发光的进一步增加。根据本发明的装置或系统包括装置（例如，激光器，光学放大器，LED），其包括平面波导，其核心区域除了包含至少90原子％Si或SiGe合金之外还包含Er，Pr和/或Nd。并且还含有C，N和/或F，并且优选还含有氧。目前优选的根据本发明的装置或系统包括用于电泵浦波导装置的装置。
主权项	An article or system comprising a device (30) that comprises optical waveguide means (32, 33, 34) adapted for guiding signal radiation of wavelength λ s, said waveguide means comprising material that contains a rare earth (RE) element selected from the group consisting of erbium (Er), praseodymium (Pr) and neodymium (Nd), the device further comprising means (35, 36, 37) for causing at least some of the RE in the waveguide means to undergo an electronic transition to an excited electronic state that is associated with luminescence; CHARACTERIZED IN THAT a) the waveguide means are planar waveguide means comprising a core region (33) comprising semiconductor material selected from the group consisting of Si and SiGe alloy; and b) the core region further comprises at least one member of the group of elements consisting of C, N, and F, said member to be referred-to as a the "co-dopant", such that the luminescence associated with the waveguide means is substantially higher than the luminescence associated with otherwise identical comparison waveguide means that do not contain the co-dopant.
