An integrated tunable C band laser fabricated in a commercial CMOS foundry is discussed. The laser is embedded in the silicon chip, and is hermetically sealed. Preliminary optical characterization results are presented. OCIS codes: (250.5960) Semiconductor Lasers; (250.5300) Photonic Integrated Circuits; (140.3600) Lasers, tunable

Utilizing boundary integral method (BIM), we investigate molecularspontaneous emission rate enhancement in the vicinity of plasmonic nanoparticles ofelliptical cross section. These types of nanoparticles can considerably enhance themolecule decay rate. The spontaneous emission rate can be modified by altering theaspect ratio of the elliptical nanoparticle, the background refractive index andnan...

Hyperbolic metamaterial (HMM), a sub-wavelength periodic artificial structure with hyperbolic dispersion, can enhance the spontaneous emission of quantum emitters. Here, we demonstrate the large spontaneous emission rate enhancement of an organic dye placed in a grating coupled hyperbolic metamaterial (GCHMM). A two-dimensional (2D) silver diffraction grating coupled with an Ag/Al2O3 HMM shows ...

The local-field renormalization of the spontaneous emission rate in a dielectric is explicitly obtained from a fully microscopic quantum-electrodynamical, many-body derivation of Langevin-Bloch operator equations for two-level atoms embedded in an absorptive and dispersive, linear dielectric host. We find that the dielectric local-field enhancement of the spontaneous emission rate is smaller th...

Using time-resolved photoluminescence measurements, the recombination rate in an In0.18Ga0.82N/GaN quantum well ~QW! is shown to be greatly enhanced when spontaneous emission is resonantly coupled to a silver surface plasmon. The rate of enhanced spontaneous emission into the surface plasmon was as much as 92 times faster than QW spontaneous emission into free space. A calculation, based on Fer...
