In the late nineteenth century, Heinrich Hertz demonstrated that the electromagnetic
properties of materials are intimately related to their structure at the subwavelength scale by …

Periodic structures with a sub‐wavelength pitch have been known since Hertz conducted his
first experiments on the polarization of electromagnetic waves. While the use of these …

Although optical technology provides the best solution for the transmission of information, all-
optical devices must satisfy several qualitative criteria to be used as logic elements. In …

On-chip mode-manipulation is one of the most important physical fundamentals for many
photonic integrated devices and circuits. In the past years, great progresses have been …

We propose an ultra-broadband multimode interference (MMI) coupler with a wavelength
range exceeding the O, E, S, C, L and U optical communication bands. For the first time, the …

" This text book has been written as lecture notes for the master and postgraduate (licentiate)
course on Metamaterials and Nanophotonics which is taught at the School of Electrical …

We provide an overview of recent work on developing integrated microwave photonic
subsystems in silicon photonics for generating chirped microwave waveforms as well as for …

In this paper, we present a review on silicon-based nonlinear devices for all optical
nonlinear processing of complex telecommunication signals. We discuss some recent …

Subwavelength grating (SWG) waveguides in silicon-on-insulator are emerging as an
enabling technology for implementing compact, high-performance photonic integrated …

In this paper, we present the design, optimization, and implementation of a sub-wavelength
grating (SWG) multi-mode interference coupler (MMI) on the silicon nitride photonic …
