University Twente
The Chair Integrated Optical MicroSystems
(IOMS), formerly known as the Lightwave Devices Group (LDG), is part of the
faculty of Electrical Engineering, Mathematics and Computer Science
(EEMCS) (Elektrotechniek, Wiskunde en Informatica
(EWI) in Dutch) at the University of Twente . The research
activities are carried out within the MESA+ Research Institute .
Research Themes Research within the IOMS
chair is organized in three research groups:
· Active Photonic Devices (Prof. M. Pollnau)
· Photonics Integration Technology (Prof. A.
Driessen)
· Sensors and Photonic Crystals (Dr.
H.J.W.M. Hoekstra)
The
research activities of the Integrated Optical MicroSystems group concentrate on
design, realization and testing of planar integrated optical devices, and on
materials connected herewith. The main application fields are optical
communications and optical sensors.
Sensors
and Photonic Crystals
The
IOMS group focuses, besides devices for the telecom, on IO sensors for the
chemical domain and also for the read out of moving parts in micromechanical
devices. So far, a large number of different sensing principles have been
proposed and, for an important part, implemented and tested. In almost all
cases the sensors have been developed in cooperation with groups supplying the
materials for sensing purposes.
It is the aim for the near future to
continue research in line with the above. New challenging sensing topics have
to be formulated which have to be interesting both from the scientific and
application point of view. Such topics will or could be:
· The further increase of sensitivity of an
IO device, down to single molecule detection.
· The application of multi-sensing arrays or
matrices, allowing the simultaneous detection of a large number of substances.
·IO devices to study in detail the behaviour
of a single molecule (reaction kinetics, (luminescent) behaviour as a function
of history).
New principles for position sensing in MEMS
devices.
In
the light of the above it can be seen that cooperation with scientific partners
focusing mainly on the study of a certain class of materials or on MEMS would
strengthen the research of the IOMS group, and could also be a source of
formulating new, challenging problems in the sensing field.
