April 2008 Koç University Microphotonics Research Laboratory's collaborative research with Harvard University is reported the Photonics Spectra Magazine. Putting Optical Communications in the Black (Photoluminescence of black silicon could make it suitable for LANs) by Hank Hogan. The computers in an office someday might be networked with light, if recent research on black silicon pans out. A group of researchers from Harvard University in Cambridge, Mass., from Koç University in Istanbul, Turkey, and from SiOnyx Inc. in Beverly, Mass., have investigated the photoluminescence of black silicon and have found a broadband that is centered at 630 nm.
