Semiconductor Fibre Devices for Nonlinear Photonics
The focus of this group’s research is to follow the development of semiconductor impregnated optical fibres from the design and characterisation stage, to the demonstration of practical all-fibre devices.
Within the group we have a full complement of experimental and numerical expertise to support the construction of a wide range of devices. We also collaborate strongly with several groups across the Faculty of Applied Physical Sciences in the area of nonlinear photonics.

Impact of research
Semiconductor photonics is fast becoming one of the most active areas of research offering optoelectronic solutions for a wide range of applications not only in telecoms, but also in medicine, imaging, spectroscopy, and sensing. For example: ultra-fast all-fibre optical switches aim to reduce costs and improve efficiency of communications systems, whilst laser sources which operate in the mid infrared are of use for environmental sensing and medical applications. The incorporation of the active semiconductor component into the fibre geometry provides an important step towards seamlessly linking semiconductor photonics with existing fibre infrastructures. Our research aims to develop elegant semiconductor fibre based devices over the range of these diverse fields to maximise impact and ensure a high level of both scientific and commercial relevance.
A wide range of optical and material characterization facilities are available that extend over the wavelength range 300nm-3.4µm. Laser sources include: supercontinuum source, femtosecond optical parametric oscillator, high power fibre lasers and laser diodes.
