The rapid development of telecommunication networks is driven by user demands for new applications and advances in technologies. The explosive growth of the internet traffic is due to its use for collecting the information, communication, multimedia application, entertainment, etc. These applications are imposing a tremendous demand for bandwidth capacity on telecommunication network. The intro...

This study examines the effect of wavelength light illuminated on DSSC absorption and gap dye energy. The used was sea lettuce anthocyanin from Sanur Beach, Bali. As much as 20 grams dried powder dissolved in 80 mL 96% ethanol 6% HCl. After 24 hours immersion, it filtered with Whatman 41 paper. filtrate characterized using a UV-Vis-NIR spectrophotometer so that wavelengths were 272.5 nm, 417 65...

Wavelength is one of the most important resources in Wavelength Division Multiplexing(WDM) networks. In optical routing, we are given a set of communication paths (or ligthpaths) in a WDM network and we must assign a wavelength to each path so that paths sharing a link must be assigned with different wavelengths. By properly choosing a set of nodes that are equipped with wavelength converters, ...

The composite cavity fiber laser (CCFL) is relatively simple in its fabrication, as it is essentially three wavelength matched Bragg gratings in a section of doped fiber. By using internal feedback with unequal sub-cavity lengths, unidirectional CCFLs with significantly asymmetric output power from its two outputs can be achieved. Preliminary results also show that it is possible for the lasing...
