SI power traceability for single photon quantum-dot emitters using a picowatt cryogenic thermal detector

The presentation will discuss our latest efforts in developing a picowatt cryogenic thermal detector for use in measuring the emitted optical power from NRC quantum-dot single photon sources, and linking this measurement directly to the SI. I will also discuss the application of frequency-programmable Josephson voltage standards to the direct measurement of the electrical substitution power of the picowatt detector Co-sponsored by: National Research Council, Canada.
