An Impressive achievement for a student at HIT

A paper based on a final project in NanoPhotonics , by Oded Katz from the Faculty of Engineering at HIT , mentored by Dr. Dror Malka, was accepted and published in the prestigious Photonics and Nanostructures - Fundamentals and Applications scientific journal.
Dr. Malka: "In this paper, we demonstrate compact silicon on insulator (SOI) 1 × 4 optical power splitter using seven horizontal slotted waveguides. Aluminum nitride (AIN) surrounded by silicon (Si) was used to confine the optical field in the slot region.
All of the power analysis has been done in transverse magnetic (TM) polarization mode and a compact optical power splitter as short as 14.5 μm was demonstrated. The splitter was designed by using full vectorial beam propagation method (FV-BPM) simulations.
Numerical investigations show that this device can work across the whole C-band (1530–1565 nm) with excess loss better than 0.23 dB."
