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.
