A Probe for Rapid and Flexible Evaluation of Photonic Integrated Circuits (PICs)

NIST Inventors
Kartik Srinivasan
The Tapered Polymer Optical Probe (TPOP) is a state-of-the-art light probe that collects light from very small, localized areas. It is a small loop of a thin plastic "string" that collects light from a localized area near the loop into a fiber optic for signal testing. The probe is made of a durable
