Cryogenic Photonic Probe Station
combined probe station and confocal microscopy
Photonic Integrated Circuits (PIC) are hot candidates for becoming
the key components of the next generation of optical and quantum
communication systems, because of the promise of very high information transfer speed, robustness and the compatibility with standard
microelectronics devices technology. Furthermore the extremely high
sensitivity of resonant nanophotonics structures to light-matter interactions makes them candidates for a new classes of sensors with broad
range of possible applications in physics, biology and chemistry. The
Photonic Probe Station, which combines two optical fiber probes and
a free optical beam Confocal Microscope (CFMI) provides an ideal,
ultra-stable, extremely compact and easy-to-use table top setup for
nano-photonic device characterization. The lensed fibers couple in
and out the light into the sample planar wave guides. The confocal
microscope allows not only for sample surface probing, but also for outof-plane coupling into photonic structures. The combination with the
attoDRY800 cryo-optical table offers a powerful easy-to-use setup
for characterization of photonic nanostructures in a temperature
range from 4 K up to 320 K.
