摘要

讨论了4 μm波长光通信的可能性。提出了在该波长具有极低损耗的光纤的新材料。提出了在可接受的增长率下不仅制造玻璃纤维,而且制造单晶光纤的可能性。描述了一种新的异质结系统,用于制造必要的探测器和高辐射源,并有可能在室温下工作。4 μm光通信比1 μm光通信的优点包括对光学对准精度的要求放宽(对单模操作尤其重要),对光纤中过渡金属杂质的容错性更大,以及减少散射损耗,因此,如果可以达到所需的纯度,则有望大大降低光纤损耗。如果能够实现接近10 - 3 dB/dm的光纤损耗,那么极长的级长(例如1000公里)应该是可能的。还讨论了光通信的其他可能波长。

Devices and materials for 4 μm-band fibre-optical communication
The possibilities of optical communication at 4 μm wavelength are discussed. New materials are proposed for optical fibres capable of very low loss at this wavelength. The possibility of fabricating not only glass but single-crystal optical fibres at acceptable growth rates is suggested. A novel heterojunction system is described for making the necessary detectors and high-radiance sources, with the possibility of room-temperature operation. Advantages of optical communication at 4 μm rather than at 1 μm include relaxed demands on the precision of optical alignment (particularly important for single-mode operation), greater tolerance of transition metal impurities in the fibre as well as reduced scattering loss, and, therefore, the promise of much lower fibre loss if the required purity can be achieved. Extremely long stage lengths, e.g. 1000 km, should be possible if, as seems likely, fibre losses approaching 10−3 dB/dm can be achieved. Other possible wavelengths for optical communications are also discussed.
