Composite metal-dielectric-semiconductor nanostructures are used to design, fabricate and test nanoscale resonators and nanolasers that utilize various modes confined in all three dimensions. Integration with silicon photonics material platform is also explored and experimentally validated.
Optics has the potential to solve some of the most exciting problems in information systems. It promises crosstalk-free interconnects with essentially unlimited bandwidth, long-distance data transmission without skew and without power- and time-consuming regeneration, miniaturization, parallelism, and efficient implementation of important algorithms such as Fourier transforms. Numerous information...
This paper explores the role of nanotechnology with focus on nanophotonics in dielectric, metal, and semiconductor inhomogeneous composition materials, devices and subsystems for optical communications, information and signal processing, and sensing.
This work demonstrates a technique that allows optical near-field characterization of devices while preserving their optical properties. To do so, a liquid overcladding is introduced to emulate the actual overcladding of the final operational device while allowing the probe to sample the evanescent field at the core cladding interface for analysis by the near-field scanning optical microscopy (NSOM)...

We demonstrate an add/drop filter based on coupled vertical gratings on silicon. The concept is extended to implement a 1 by 4 wavelength division multiplexer with 3nm bandwidth, 1dB insertion loss and 16dB crosstalk suppression.
A wavelength selective add/drop filter based on coupled vertical gratings is proposed for applications in wavelength division multiplexing on silicon. We demonstrate tailoring of device bandwidth and channel location.
We introduce an optical microcavity on a chip created by a waveguide terminated with metallic mirrors. The cavity shows high potential for biochemical sensing.
Optofluidic 1times4 switch made of a blazed grating in silicon elastomer integrated with microfluidic channel was designed, fabricated and tested. Experiments show 1.7 dB insertion loss, extinction ratio of 9.8 dB, and response time 60 ms.
We present different techniques for fabricating long-range plasmonic waveguides. Due to the requirement of symmetric cladding, fabrication is highly dependent on the material system used. Results are given for materials such as SU8 and polydimethylsiloxane.
Different jitters terms are widely used for jitter characterization, -edge jitter, cycle-to-cycle jitter, period jitter are just a few of them. These jitter conventions have been studied in many publications considering jitter measurements, but they lack a common mathematical basis which should include both - the relations of these terms with jitter spectrum typical for measurement practice, and some...
Jitter measurement with different time domain instruments (TDI) have been extensively studied in numerous works. These works covered different measurement instruments including equivalent-time (ETO) or sampling and real-time oscilloscopes (RTO), time interval analyzers (TIA), etc. However, in the published papers there is a lack of analysis of jitter transformations in different TDIs. Some publications...
