PECASE: Resonantly-Enhanced Lanthanide Emitters for Subwavelength-Scale, Active Photonics
Abstract
With the support of this grant, we: (1) developed energy-momentum spectroscopy, a new angle-resolved spectroscopic technique that allows for the determination of the strength, order, and orientation of electronic transitions in quantum emitters, (2) leveraged the spectrally distinct electric and magnetic dipole transitions in Eu3plus:Y2O3 to tune emission spectra and to modulate emission at sub-lifetime speeds, (3) performed detailed quantum-mechanical calculations in the intermediate coupling regime to identify strong magnetic dipole emission lines for future experimental studies, (4) informed by these calculations we used energy-momentum spectroscopy to characterize electric and magnetic dipole contributions to Dy3plus:Y2O3 and Tm3plus:Y2O3 emission, (5) demonstrated spectral tuning of the highly mixed ED/MD telecom emission from Er3plus:Y2O3 by varying the distance to a gold mirror with a Y2O3 spacer layer, (6) realized all optical modulation of Er3plus:Y2O3 (at over 3 orders of magnitude faster than its excited state lifetime) by leveraging the ultra-fast VO2 insulator-metal phase transition, and (7) expanded energy-momentum spectroscopy to a larger range of quantum emitters by removing the entrance slit of the imaging spectrograph and using convex optimization to extract information from the multiplexed image, thus greatly increasing optical throughput.
