OptoFab Node

OptoFab consists of four centres of facilities and expertise based at Macquarie University, Bandwidth Foundry International, University of Sydney and the University of Adelaide with the headquarters at Macquarie University. We offer services in four key areas of expertise.

The Node offers specialist dedicated staff that are on hand to provide services & technical support to users where appropriate in microprocessing and microfabrication of fibre, planar and bulk optical materials which include silica, silicon, lithium niobate and polymers. There are also a number of post-processing capabilities e.g. surface functionalisation and advanced characterisation. These techniques have been used to produce artefacts for use in telecoms, biotechnology, biomedicine, microelectronics, optical sensing, industrial processing, defence and security applications.

Laser Micromachining and Inscription

The node specialises in short and ultra-short pulsed laser micromachining in the UV, visible and IR micromachining and inscription in a range of materials including metals, ceramics, polymers, glasses and crystalline materials. Typical feature sizes are between 10µm - several mm.

The key services on offer are:

  • Laser micromachining (Nanosecond and femtosecond)
  • Femtosecond point by point fibre Bragg gratings
  • Femtosecond laser written waveguides.

This work is carried out at OptoFab @ Macquarie University.


Providing prototyping facilities and services to developers of photonics integrated circuits. The group specialises in photolithography foundry services including photomask production and direct laser writing of optical materials.

Services offered include provision of external access to:

  • direct-write photolithography using a Heidelberg Instruments DWL 200, a proven quality manufacturing tool used worldwide for mask making and direct writing. The facility produces structures with a resolution down to 0.4 µm in its class 100 clean room.
  • High Resolution optical lithography with a new ASML i-line stepper system.

This work is carried out at OptoFab @ Bandwidth Foundry International.

Speciality Optical Fibre Production

The node specialises in the production of a range of optical fibres and preforms in Silica, soft glasses and Polymers. A range of the key services offered are listed below:

Speciality & Functional Optical Materials
