ANFF ACT facility provides a range of capabilities and services for the micro/nanofabrication of photonic and related devices as well as the fabrication of waveguides and photonic crystals.

The node, located at the Australian National University, specialises in photonic/electronic materials growth, and the processing and fabrication of devices including micro electro-mechanical systems (MEMS). These capabilities provide a range of services for the fabrication of photonic and related devices as well as the production of waveguides and photonic crystals.

ANFF ACT works closely with two renowned research groups based at ANU’s Laser Physics Centre and the Department of Electronic Materials Engineering. These groups bring expertise in the capabilities of high-energy ion implantation, Si-etching, optical characterisation and two metal organic chemical vapour deposition (MOCVD) reactors for the growth of III-V compound semiconductor multilayers based on: GaAs, AIGaAs, InGaAs, InP, InGaAsP, InAlGaAs, GaSb, InSb, InGaAsN. These reactors enable the fabrication of nanowires, quantum dots, quantum wells, strained layers and devices.

Node Competencies
