  • Fiber Optic Transciever

    Advanced IC Engineering

    The ADVICE Fiber Optic Xcvr (FOX-1) is a photoelectric fiber optic transceiver. It is designed to transmit and receive 660nm (visible) light using standard plastic fiberoptic cable. The FOX transmits light on one fiber, which reflects off a target, and then returns on a second plastic fiberoptic cable. The FOX has a sensitive receiver that converts strong/weak reflected light amplitude into high/low voltage pulses on its electrical interface. Unlike similar sensors, the FOX does not require any calibration for correct operation. The FOX is designed to work in low-light and low-contrast applications where optical pulse rates are between 1Hz and 100kHz.

  • Optical Isolators


    Optical Isolator is a passive optical component that allows light to transmit in a certain direction while block light in the opposite direction. The working principle is based on the non-reciprocity of Faraday rotation. The light sources from back reflections and signals, which can cause instabilities and damage, can be well isolated by optical isolator through utilizing the Faraday effect of magneto-optical crystal. The Polarization Insensitive Isolator features low insertion loss, high isolation and excellent environmental stability and reliability. It is ideal for suppressing back reflection in fiber lasers and other high performance laser based fiber optics systems.

  • Erbium Doped Fiber Amplifier

    EDFA - Fibotec Fiberoptics GmbH

    EDFAs are based on the light amplification in erbium-doped fiber, which are optically pumped by means of 980 nm or 1480 nm light sources. In this way, the light of a larger wavelength within the C or L band applied to the input of the amplifier is amplified, thus widening the range of optical communication links. EDFAs typically operate in saturation and the average signal power determines the average gain. The dynamics of EDFA are unaffected by the sequence and dynamics of a digital signal or channel interaction in DWDM systems. As a result, multiple channels can be bundled within the total erbium spectral amplification bandwidth. However, the total average output power in both cases is determined by the saturation power of the specific EDFA.

  • The Nanoworkbench

    Klocke Nanotechnik

    In light microscopy it is natural to use toolsets like tweezers, knives, probes and several different measurement tools. Without this many present-day products and methods would not exist. The operators of SEM/FIB-Systems generally work without toolsets, although the wavelength limit of light is no physical boundary. It can be imagined how technology would be pushed when a SEM/FIB Workbench reaches the same degree of practicability and utilization as toolsets for light microscopes. The Nanoworkbench is the first system substituting the eye-hand coordination effectively with nm precision in a SEM/FIB-system. The Nanoworkbench features a set of applications including TEM lamella preparation, nano probing, nano cutting, nano cleaning, force distance measurement, particle sorting and material preparation. Every application supports automated processes so almost no user interaction is needed. Even complex processes can be done within seconds and even by untrained users. Applications can be combined to create new and more complex processes. Expanding the SEM/FIB to a material processing system and a nano-analytical workbench by utilizing the Klocke Nanoworkbench enables new applications in research and production of material research, live sciences, tribology, environmental & forensic research and semiconductor technology.
