Achieving optical gain in waveguide-confined nanocluster-sensitized erbium by pulsed excitation
We use a rate equation approach to model the conditions for optical gain in nanocluster sensitized erbium in a slot waveguide geometry. We determine the viability of achieving net gain for the range of reported values of the carrier absorption cross section for silicon nanoclusters. After accounting for the local density of optical states modification of the emission rates, we find that gain is...
متن کاملC- and L-band erbium-doped waveguide lasers with wafer-scale silicon nitride cavities.
We report on integrated erbium-doped waveguide lasers designed for silicon photonic systems. The distributed Bragg reflector laser cavities consist of silicon nitride waveguide and grating features defined by wafer-scale immersion lithography and a top erbium-doped aluminum oxide layer deposited as the final step in the fabrication process. The resulting inverted ridge waveguide yields high opt...
متن کاملVisible and 1.54 μm Emission From Amorphous Silicon Nitride Films by Reactive Cosputtering
In this paper, we present our main results on the structural and optical properties of light-emitting amorphous silicon nitride (SiNx) films fabricated by reactive magnetron cosputtering. In particular, we discuss the origin of the visible emission in amorphous silicon nitride films and investigate the optical emission properties of Erbium-doped amorphous silicon nitride (Er:SiNx). The mechanis...
متن کاملNear-field enhancement of infrared intensities for f-f transitions in Er3+ ions close to the surface of silicon nanoparticles.
Erbium doped waveguide amplifiers can be used in optical integrated circuits to compensate for signal losses. Such amplifiers use stimulated emission from the first excited state ((4) I (13/2)) to the ground state ((4) I (15/2)) of Er(3+) at 1.53 µm, the standard wavelength for optical communication. Since the intra-f transitions are parity forbidden for free Er(3+) ions, the absorption and the...
متن کاملCorrelation between the optical loss and crystalline quality in erbium-doped GaN optical waveguides.
Erbium-doped GaN (GaN:Er) epilayers were synthesized by metal organic chemical vapor deposition. GaN:Er waveguides were fabricated based on four different GaN:Er layer structures: GaN:Er/GaN/Al2O3, GaN:Er/GaN/AlN/Al2O3, GaN:Er/GaN/Al(0.75)Ga(0.25)N/AlN/Al2O3, and GaN/GaN:Er/GaN/Al2O3. Optical loss at 1.54 μm in these waveguide structures has been measured. It was found that the optical attenuat...
