德國AIFOTEC GmbH
AIFOTEC 有限公司主要開發、生產、推廣和銷售光導纖維元件，重點領域是能減少廢料、降低成本、減少能量消耗的新組裝技術的應用。
今天，光電子設備主要依靠激光焊接技術制造。使用這項技術，所有的元件必須在光具座上進行排列組合，然后使用激光束焊接方法加以固定。由于所有的元件固定器都是鋼鐵材質的，因此一些巨型元件就要受到焊接能力和機械穩定性的限制。所有的元件都必須在次微米的范圍內
進行排列組合和固定加工，這就增加了材料、人員和機械的成本，同時大大降低了產量。整個組裝過程在高頻饋通的密封環境下進行，很像過去“電子管時代”電子元件的制造過程。與上述情況相比，AIFOTEC 有限公司開發出了一種“硅元素平臺技術”，該技術使用具有創新性的高精確激光低溫焊接技術和圖像識別技術，可以非常精準地制造光學元件。另外，它還結合了全球最高級的粘合加工過程。通過“硅元素平臺技術”，AIFOTEC 有限公司制造出一種使用HIT（混合式集成技術）的工具加工裝置。與傳統機器相比，它的體型較小，效果較好，成
本較低。
AIFOTEC 有限公司運用該技術生產的第一個工具加工裝置為FGL（纖維光柵激光器）。它由SSCL（光點直徑轉換激光器）組成，包括一個半導體增益元件。由于擁有這樣一種特殊的裝置，光線可以不需要透鏡、透鏡纖維等聯結物而直接照射到纖維上。纖維中的波長被布拉格光柵所
選擇。這種ECL（外腔式激光器）裝置可以以很低的成本實現遠距離傳輸、高調制速度和密集的波長光柵。
AIFOTEC 有限公司也為包括有特殊要求的FGL（纖維光柵激光器）產品在內的其它產品（如：傳輸器與接收器的光學組件）、其它平臺（如硅、玻璃和陶瓷）和包括纖維光學通訊與數據通信應用在內的其它市場（如測試、測量與自動化等）提供HIT（混合式集成技術）技術開發與
設備研制服務。
AIFOTEC GmbH is developing, producing and marketing fiberoptic components. Hereby the
focus lies on the application of new assembly technologies for the reduction of footprint, costs
and power dissipation.
Optoelectronic devices are nowadays mainly produced by means of laser welding. With this
technology all parts have to be aligned on some sort of optical bench and are then fixed by
welding with a laser beam. This leads to rather bulky components as all component holders
are made of steel parts for weldability and mechanical stability. All components have to be
aligned and fixed in the submicrometer range which leads to rather high material, personnel
and machine costs as well as reduced yield. The whole assembly is then packaged in a
hermetic housing with high frequency feed-throughs. This whole assembly setup has an
analogy to the “old days” of electronic components when radio tubes were standard devices.
In contrast to this setup AIFOTEC has developed a Silicon Platform Technology which,
in combination with innovative High Precision Laser Soldering Technology and image
recognition, enables high accuracy placements of photonic components. In combination with
innovative processes like Glueing and Globe Top Processes this gives a toolset which solves
the tradeoff between smaller devices with better performance and lower costs by using a
Hybrid Integrated Technology (HIT) approach.
AIFOTEC?s first product out of this technology toolset is the so-called Fibre Grating Laser
(FGL) which consists of a semiconductor gain element, integrated with a spot-size converter
(Spot Size Converter Laser, SSCL). With this unique setup the light can directly launched
into the fibre without any coupling elements like lenses, lensed fibres etc. The wavelength is
selected by a Bragg grating in the fibre. This Externally Cavity Laser (ECL) setup enables
high transmission distances, high modulation speeds and dense wavelength grid at low costs.
AIFOTEC also offers HIT development and manufacturing services for other products besides
the particular FGL (e.g. transmitter and receiver optical subassemblies) other platforms
(e.g. Silicon, Glass and Ceramics) and other markets besides fiberoptic tele- and datacom
applications (e.g. test & measurement, automotive etc.).
