Large exciton longitudinal–transverse splitting enables room-temperature ultrafast coherent polaritonics in layered perovskite crystals
Phillips, D. F., Fleischhauer, A., Mair, A., Walsworth, R. L. & Lukin, M. D. Storage of light in…
Ultra high-Q tunable microring resonators enabled by slow light
Slow light-induced linewidth narrowing The maximum achievable Q-factor (Q = ωc/κ) of resonators is primarily constrained by intrinsic loss mechanisms…
