Research Activities

Short Summary of Current Research Activities

a) Software for the calculation of gain, refractive index change and current in semiconductor laser diodes and amplifiers has been developed. Software for the simulation of light propagation (BPM) has also been developed. Filamentation process is currently been investigated using that software. Current distribution in the cross-section of a laser diode is also under research. The goals are to determine the basic features of the filamentation in semiconductor laser amplifiers and to find better structures and geometries.

b) A novel design of a fast (about 30Gb/s) silicon optical modulator of the length as small as  (using the applied voltage of 2V) has been proposed. A design of ultra-short optical switch has also been proposed. The feasibility of the devices has been shown. Required fabrication tolerances have been determined. We are preparing for the fabrication of prototypes.

c) A new type of optical fiber has been proposed. The light confinement is based on a kind of anti-resonance in the cladding. The fiber is characterized by a (possible) large core diameter while in the single-mode regime. The fiber can be hollow. Currently we are working on the determination of the dispersion curve, losses, required fabrication tolerances and are looking for applications.

Short Summary of Past Research Activities

Oscillatory instabilities in dc-biased quantum dots (in collaboration with the Ben – Gurion University, the Rutgers University and the Oxford University):

A ‘quantum dot’ in the Coulomb blockade regime, subject to an arbitrarily large source–drain voltage V was considered. When V is small, quantum dots with odd electron occupation display the Kondo effect, giving rise to enhanced conductance. We investigated the regime where V is increased beyond the Kondo temperature and the Kondo resonance splits into two components. We showed that interference between them resulted in spontaneous oscillations of the current through the dot. Our theory predicts the appearance of ‘Shapiro steps’ in the current–voltage characteristics.

Photonic crystals (PhCs) (in collaboration with the Soreq NRC):

a) A computer code for the simulation of chemical etching process was developed. The code was used in the Soreq NRC for the search of novel PhC structures and for the interpretation of experiments.

b) A technique and a computer program for the check of the bi-continuity of a PhC which can be fabricated by means of the 4-laser-beam lithography technique were developed. We also developed a method and a computer program for removing of the disconnected regions from the model.

c) Computer software for the calculation of the band – structure (optical properties) of PhCs was developed. The software was used in the Soreq NRC.

d) Two omnidirectional dielectric mirrors for multiple frequencies were designed. We developed a model and, using it, found non-trivial structures. The pertinent experiments were performed in the Soreq NRC and in the Ben-Gurion University.

e) We participated in the design of a new hollow PhC waveguide. The work on the fabrication of the designed waveguide was carried out in the Soreq NRC.

d) A new method of design for the phase-matching was proposed. It was implemented for PhC waveguides.

e) A two – dimensional PhC which allowed dispersion compensation (in transmission) with 10 fold better efficiency than the conventional Bragg gratings was found.
