Exciton–erbium coupling and the excitation dynamics of Er3+ in erbium- doped silicon-rich silicon oxide

Erbium doped silicon nanoclusters for Microphotonics

To my parents Cover: contour plot showing the simulated number of excited Er ions per Si nan-ocluster, as a function of Er concentration and pump power. Brighter gray tones represent higher values. More details can be found in Fig. 4.26 within this thesis, on page 102. The work described in this thesis was mainly performed at the Laboratory for MAterials and Technologies for the Information and...

Erbium-doped silicon nanocrystals in silicon/silicon nitride superlattice structures: Light emission and energy transfer

In this paper, we discuss optical emission, energy transfer and electroluminescence from a superlattice structure containing small ( 2nm diameter) amorphous silicon (Si) clusters coupled to erbium (Er) ions. The superlattice structure is fabricated by direct co-sputtering of thin ( 3–5nm) Er-doped siliconrich nitride/Si (Er:SRN/Si) layers subsequently annealed at different temperatures in order...

Monolithic erbium- and ytterbium-doped microring lasers on silicon chips.

We demonstrate monolithic 160-µm-diameter rare-earth-doped microring lasers using silicon-compatible methods. Pump light injection and laser output coupling are achieved via an integrated silicon nitride waveguide. We measure internal quality factors of up to 3.8 × 105 at 980 nm and 5.7 × 105 at 1550 nm in undoped microrings. In erbium- and ytterbium-doped microrings we observe single-mode 1.5-...
