DOWNLOAD EBOOKThe day when fiber will deliver new, yet now only foreseeable, broadband ser vices to the end user is getting nearer and nearer as we make our way towards the prophetic year 2000. Step by step, as we move from first generation lasers and fibers to the by now common erbium-doped fiber amplifiers, looking forward to such things as wavelength multiplexing and solitons, photonic switching and optical storage, the community of researchers in optical communications has stepped into the era of photonic networks. It is not just a question of terminology. Optical communication means tech nology to the same extent that photonic network means services. If it is true that information is just as marketable a product as oil or coke, the providing of an extensive global information infrastructure may end up having an even greater impact than the setting up of a world-wide railroad network did at the beginning of the industrial era. Just like wagons, bandwidth will be responsible for carrying and delivering goods to customers. The challenge for all of us in this field is for it to function in every section of the overall network, transport, access and customer area, in the best possible way: the fastest, most economical and most flexible. New services provided by a new network that exploits the potential and peculiarities of photonics surely requires a rethinking of solutions, new ideas, new architec tures, new design, especially where electronics is still dominant, as in transport and access networks.

DOWNLOAD EBOOKThe application of acousto-optic tunable filters for shaping of ultra-fast pulses in the time domain is analyzed and demonstrated. With the rapid advance of acousto-optic tunable filter (AOTF) technology, the opportunity for sophisticated signal processing capabilities arises. AOTFs offer unique processing functions, since they may be designed for operation at 1.55 micrometers and allow the simultaneous handling of up to 100 frequency channels with a high spectral resolution and with processing times of a few microsec, i.e., some three orders of magnitude faster than possible with any other technology. Previous applications of the multi-channel capability of the AOTF have concentrated on narrow-bandwidth optical signals like-in gain equalization of erbium doped fiber amplifiers. Here we show that AOTFs can also be used for the manipulation of ultrashort optical pulses by correlated amplitude and phase filtering of the multiple optical frequency components composing the ultrashort pulse. To our knowledge this is the first demonstration of the AOTF for ultra-fast time-domain signal processing.

DOWNLOAD EBOOKThis report covers Phase II work for the development of dynamically reconfigurable WDM components based on the use of collinear beam acousto-optic tunable filters (AOTF). These include optical add and drop multiplexers (ODM), optical cross-connects (OXC), and dynamic fiber amplifier equalizers (DFAE). The project included three tasks: (A) AOTF performance improvement: new designs and fabrication techniques were investigated. A demonstration model 100 GHz channel spacing AOTF was constructed that achieved 0.5 nm FWHM,
