Photonic Probe Station

vacuum shroud for photonic probe station incl. optical side access

Photonic Integrated Circuits (PIC) are hot candidates for becoming the key components of the next generation of optical and quantum communication systems. The Photonic Probe Station vacuum shroud allows for integration of two optical lensed-fiber probes from the side for coupling light into planar waveguides, and a free-beam confocal top access for nano photonic device characterization. In addition, the vacuum shroud offers side access with an additional room temperature objective from the outside.
