No physicist here but I think there may be losses in the interface air/glass. Also, air contains water and other elements that may present too much attenuation at 1550 nm. I suspect the different lambda is one of the reasons of the limited bandwidth of the hollow fiber. I should try to RTFA.
- timthorn 14y agoIt's overcoming the losses in the interfacing that's the innovation here - holey fibres have been around for a while. Note that it's the same research lab doing this work as invented the EDFA in the first place.
