Nonvolatile flash memory technology is widely used in our daily life. Following the recent progress in silicon photonics, there is now an opportunity to embed flash memories also in photonic applications. As of today, chip scale photonic devices, e.g., micro‐resonators, are becoming essential building blocks in modern silicon photonics. However, their properties, such as their resonance frequencies,...
A new post processing approach for resonance trimming of a micro-ring resonator is presented. The approach is based on charge trapping in thin layer of silicon nitride as done in Flash memories device.
We present a first demonstration of plasmonic enhanced internal photoemission Schottky photodetector implemented by low temperature deposited amorphous silicon for the telecom regime. The detector show responsivity of 53μA/W.
The rapidly growing interest in the mid-IR (2–5μm) wavelengths brings about the need for cheap and CMOS compatible photodetectors. Hereby we demonstrate a plasmonic enhanced Schottky detector in silicon for the mid-IR.
We demonstrate an integrated four quadrant detector in silicon for infrared light, based on integration of plasmonic splitting, focusing and plasmonic enhanced internal photoemission detection on a single silicon plasmonic chip.
We report on the sub Doppler transmission characteristics of a pump-probe V-type surface plasmon and atomic system. Suppression and subsistence of EIT windows is demonstrated due to the unique character of the plasmonic-atomic hybrid system.
We demonstrate the coupling of Surface Plasmon and Atomic resonances in the presence of magnetic fields. By enhancing light-vapor interactions, the device shows promise in high resolution vector field imaging, magnetometry and tunable optoelectronic applications.
We observe for the first time the near field optical intensity distribution of silicon nanophotonic devices operating in the mid-IR spectrum using our scanning thermal microscopy and demonstrate its advantages over conventional NSOM technique.
We demonstrate variety of light matter interactions in our nanophotonic-atomic hybrid system, considering both plasmonic and guided mode interaction with hot vapor.
Linear and non-linear Fano interactions in a hybrid system consisting of surface plasmonic resonance and alkali vapor are presented. Using a pump probe apparatus, Doppler free lineshape and all optical modulation is experimentally demonstrated.
We observe directly for the first time optical near field in silicon nanophotonics devices with nanoscale resolution using near field scanning thermal microscopy and demonstrated its advantage over the NSOM technique.
We experimentally demonstrate the planar focusing of Surface Plasmon Polaritons using space variant PMMA subwavelength features on top of a metallic film. Focusing is obtained by creating an effective graded refractive index profile.
We study light transmission through circular metallic grating under radial/azimuthal polarization illumination and observe strong polarization selectivity and a resonance behavior making it attractive for applications relying on radial polarization.
