In the present talk, we will demonstrate a hybrid integration platform combining
low-loss SiN photonics and semiconductor nanocrystals, also known as colloidal quantum dots (QDs).
Based on this platform, we demonstrate on-chip integrated SiN-QD microdisk lasers with low threshold.
This opens up a path towards realizing on-chip laser sources operating in a wide wavelength range,
combining the advantages of gain-spectrum tunability in QDs and the spectrally broad operating range of
low-loss SiN photonics. Moreover, the presently developed approach, together with our QD patterning
technique, can be used for integrating a few QD emitters with SiN PICs for laser demonstration at a few
or even single dot level and also for on-chip quantum emitters, as currently being investigated in our
group. The demonstrated active SiN-QD building blocks will open up new opportunities for both
fundamental studies and practical applications.
