Application Examples Integrated Laser Beam Combiner An example for the PIC device for visible light is the integrated laser beam combiner (ILBC). It can combine up to eight different (visible) input wavelengths into one single mode polarisation maintaining output fibre. Ideal for a system where light of different wavelengths has to be transported to a single target (e.g. a confocal microscope). See figure 4 above.
Variable Optical Attenuator Another example of using PIC technology for visible light is the Variable Optical Attenuator (VOA) for visible wavelengths. This VOA enables to decrease the output power of any input laser in a measurement setup, while the laser operates at standard high output powers. This increases the stability of the total system as the lasers prefer operation at their ‘sweet-spots’, which typically are high power. However for many applications these higher powers can damage your (biological or medical) samples.
