Lab Mission
The objective of the Photosens Laboratory is the characterization and test of optical chip devices to be implemented as miniaturized reading units for wearable sensors to measure relevant parameters for health and well-being such as temperature, physiological signals, and motion of body parts. To make these sensors wearable, the reading units need to be dramatically miniaturized to small chips. These chips require a low vibration optical table, with micrometer-controlled arms for aligning the optical and electrical probes to the chip ports.
Devices
Chip characterization setup
An optical table model Thorlabs B90180N (90×180 cm) with an antivibration system to reduce vibrations. The system also includes a system of optomechanic components for aligning optical fibers and electrical probes to the chip with micrometer resolution. The system also includes a long-working distance microscope for aligning the elements.
High resolution Optical Spectrum Analyzer
A high-resolution optical spectrum analyzer allows a precise characterization of optical devices implemented on the chip. The model is Apex AP2061A, with 5MHz resolution in the C+L optical bands.
