Research at CUDOS @ MQ

CUDOS @ MQ runs a major research program in fundamental and applied photonics developing next-generation devices for use in a variety of applications. Our current research themes are listed below.

Waveguide Laser Development

Inscribing multi-wavelength & narrow linewidth waveguide lasers in rare-earth doped glasses using femtosecond laser pulses for application in gas sensing, spectroscopy, optical communication, Terahertz generation & molecular fingerprinting.


Removing 'light pollution' from astronomical observations with laser written chips by integrating photonic lanterns, pupil remappers and waveguide Bragg-gratings.

Quantum Integrated Photonics

Using photonics to explore the exciting applications of quantum science.
Creating chip-scale devices to generate useful polarisation-entangled photon pairs & single photon sources.


Optical condensed matter science devoted to optical phenomena on the nanoscale in nanostructured metal systems. Applications may include sensing, biomedical diagnostics, nanoantennas for light-emitting diodes, etc.

Optical Nerve Stimulation

Targeted nerve stimulation via infrared laser light is an ongoing research stream within CUDOS @ MQ. Possible application includes fabricating medical prosthetics with enhanced functionality.

Magneto Optics

Fabricating laser written waveguides in nonlinear soft glass which act as optical isolators based on the Faraday effect.

Laser-Material Interactions

Understanding material modification by high intensity laser pulse using Raman spectroscopy. Also investigating optical characteristics and applications of plasmonic based structures.

Fibre Devices

Utilising femtosecond laser beams to induce refractive index modulations in the core of optical fibres to create various types of Bragg-gratings used in sensors & fibre lasers.

General Passive Devices

Taking advantage of the 3D capabilities of the direct-write platform to fabricate a multitude of application based devices. These include directional couplers & birefringent waveguides.
