The use of network connections is set to expand rapidly in television. At the same time television is changing faster than ever with new formats, DTV and high definition on the horizon. The object is to specify and create an open network appropriate for today's requirements as well as meeting tomorrow's growing, and more demanding needs. This has to work in parallel with the existing connections to provide additional I/O and without compromising their performance. For economy and compatibility the base technology should come from the computer industry but the choices require careful study. Quantel's work has resulted in Clipnet which is aimed at more efficient operation and better access to material. © 1999 Society of Motion Picture and Television Engineers, Inc. Source

Presented is a new dual-frequency laser based on an erbium-doped distributed feedback fibre laser operating on two orthogonally polarised eigenstates around 1.55m, exhibiting a frequency offset in the microwave domain. The beatnote in the free running regime between these two optical waves allows the generation of an RF signal around 1GHz with a RIN lower than -115dB/Hz over the frequency range 50kHz to 10MHz and a phase noise of -67dBc/Hz at 10kHz of the RF carrier. Up to 600MHz tunability of the beatnote is obtained by mechanical stress applied to the cavity. © 2011 The Institution of Engineering and Technology. Source

High Power Laser Diodes (HPLD) are increasingly used in different fields of applications such as Scientific, Industrial, Medical and Defense. Our significant performances improvements (especially in peak power, divergence and efficiency) and a reproducible manufacturing process have led to reliable, highly robust components. For industrial applications these devices are used predominantly for pumping of solid state lasers. Due to the drastically falling price per watt they are more and more replacing flash lamps as pump sources. Their compact size and high reliability make diode laser arrays ideally suited to this demanding market. For Scientific applications, the brightness as well as the cost are the two main drivers. In order to respond to this demand, QLD has focused its development on very high peak power bars associated with very high E/O efficiency. The level of energy QLD is achieving now has also pushed us to develop a power supply driver able to operate such diodes at up to 1000A under 100V. © 2013 The Optical Society. Source
