Nanophotonic Devices Group

The Nanophotonic Devices group designs, fabricates, and characterizes semiconductor optical devices such as new lasers, waveguide devices or sensors for various applications.

We work on quite a range of topics from advanced passive devices for frequency and spatial domain light manipulation to complex integrated optoelectronic components with tailored material responses to allow light emission and light control also directly in the temporal domain.

We use the best in class materials for the various topics, i.e. silicon and III-V semiconductors (InP, GaAs and GaN)

Besides advanced device concepts a main focus area is understanding and perfecting cleanroom processes to allow engineering at the nanoscale.

Picture of the Month

The Nanophotonic Device group was part of the team winning the Horizon2020 prize for “Breaking the optical transmission barrier”. An AlGaAs nanowire was use to increase the bandwidth in an energy efficient way. Link

MOVPE program and mask layout

Design

Design of devices: Optical, electrical and mechanical simulations, mask design, epitaxial design.
Yellow room

Fabrication

All our research projects have an element of synthesis, i.e. typically fabrication activities in the Danchip cleanroom. The group is running the MOVPE system and has extensive knowledge within e-beam lithography, dry etching and complex electro-optic  device geometries.
Probing station

Characterization

We characterize both materials and devices using a number of test stations. Setup for planar devices, edge-emitting lasers, VCSELs, mode-locked lasers and micro-PL have been built.
