PhD Position in Optics/Photonics at Royal Institute of Technology, Sweden, KTH

The main project goal is to develop state-of-the-art silicon compatible switches and modulators for high-speed (40 Gbit/s + modulation) with small footprint and low energy dissipation for fiber-optic communication and computer interconnect systems. To improve the efficiency of devices, slot waveguide configuration will be investigated. Organic electro-optical materials incorporated in silicon photonic waveguides provide potential means of achieving ultrafast tuning in a very compact device. The optical field intensity in a structure with feature size of the sub-wavelength scale (on the order of 20–180 nm) tends to concentrate within the low-index slot for the polarization perpendicular to the slot. Such a sophisticated design in combination with an enhanced electro-optical response of novel polymer materials (appr 10 times as large as in Lithium Niobate) give orders of magnitude lower power dissipation, a key feature in today’s systems.

Applicants must hold or be about to receive an MSc degree in optics/photonics, applied physics, electrical engineering, or related areas. Furthermore, the applicant must have:

* Strong academic credentials, written and spoken English proficiency, communication and team-work skills.

* Interest in following subjects: electro-optics, integrated and waveguide components for photonics, optical communication. Strong motivation to run experimental research.

* Background in several of the following: optics/photonics, micro-optics, light polarization, electromagnetism, fiber optics and optical waveguiding components, microwave engineering.

* Experience with integrated devices (optics and/or microelectronics), waveguide fabrication and testing, measurement methods in optics and fiber optics, as well as basic knowledge of the laser physics and physics of polymers will be considered as advantages.
