This article focuses on of hollow-core photoniccrystal fibers (HC-PCFs). With air cores, such fibers mostly avoid the problem regular solid-core fibers have, which is that of glass absorption (resulting in a minimum optical attenuation for solid-core glass fibers of 0.15 dB/km). The researchers measured surface roughness inside a HC-PCF with an atomic-force microscope, performed angular-resolved scattering measurements on a HC-PCF having an attenuation of 1.7 dB/km at 1565 nm (cross section is shown; horizontal bands within the core are imaging artifacts), and measured attenuation spectra.

The article presents questions with answers from an expert related to photonics industry. The questions in this article are related to funding of companies from the photonics industry. The expert says that several well-financed switch companies that formed during the bubble are having a hard time getting additional funding to stay solvent, so it is doubly hard for a new startup to get funded. Getting a bridge loan from small investors is enormously risky for everyone involved. There for recommendation is to incubate invention in an enterprising way, such as in a university laboratory, until a substantial amount of money lined up to bring project to a meaningful conclusion.
