Our design and simulation work is carried by a combination of various simulation tools that are available to us, e.g. plane wave expansion (PWE), rigorous coupled wave analysis (RCWA), and finite difference time domain (FDTD) codes.

Nano Fabrication

We fabricate our samples in house at the Hebrew university the micro fabrication laboratory of the applied physics department (equipped with MJB3 mask Aligner, wet benches, oxidation and diffusion ovens, e-gun evaporator and LPCVD system) and the unit for nanofabrication at the Hebrew University Nanocenter, (equipped with e-beam lithography and photolithography tools, metal deposition instruments, RIE/ICP, PECVD, glove box, packaging tools, and characterization tools, e.g. profiler, microscopes, thickness measuring instrument, probe station, etc.)

Experimental characterization

We characterize our devices in the nanophotonic characterization laboratory headed by Uriel Levy. The lab was established in 2007. It includes 4 optical tables and state of the art characterization equipment including large variety of lasers in the UV, visible, and the near IR range (including a Ti-Sapphire laser, Pulsed Nd-YAG lasers and tunable semiconductor lasers), optical spectrum analyzer, fast oscilloscopes, power sources, function generators, CCD cameras, fiber-waveguide alignment system, and microfluidic assemblies for operating microfluidic devices. Our lab is equipped with a near field scanning optical microscope (NSOM).

Structural characterization

For structural characterization we use the unit for nano characterization at the nanocenter of the Hebrew University. Primarily we use the high resolution SEM and the AFM.
