Hollow waveguides and micro-cavities for optofluidics

2015/16-2018/19 • $88,000 • PI
The proposed research lies at the increasingly important intersection between integrated optics, micro-electromechanical systems (MEMS), and microfluidics. Our long-term aim is to demonstrate complex ‘optofluidic systems on a chip’ by targeting close integration of optical devices (e.g....

A wavelength interrogator for optical sensors

2016/17 • $118,000 • PI,CO
Optical sensors - such as those based on fibre Bragg gratings - are gaining commercial importance due to attributes such as immunity from electromagnetic interference, small size and weight, chemical resistance, and ability to operate at extreme temperatures. They play a key role in a number of...

Devices for optofluidic micro-systems

2010/11-2014/15 • $130,000 • PI
We propose research on hollow optical waveguides, and will study their utility for new optical detection strategies in lab-on-chip (LOC) systems and as optical interconnections within electronic computing systems. The proposal builds on recent work in our lab, which produced new strategies for...

Development of an interferometer for the detection of structured beams

2014/15 • $25,000 • PI
The proposed work involves the design, implementation and test of a novel optical platform targeting thedetection of sub-micrometer scale particles using a structured laser beam (such as a dark or donut beam).Particle detection systems that utilize structured laser beams to enhance sensitivity...

Development of optical filters for hyperspectral imaging

2013/14 • $25,000 • PI
The proposed work involves the design and optimization of optical filters for multi-spectral and hyper-spectralimaging applications. In multi-spectral or hyper-spectral imaging, multiple wavelength-resolved images(representing the light emitted in various bands of the electromagnetic spectrum)...



An optical band-pass filter based on admittance-matched tunneling through a low index layer (typically an air layer). The admittance-matching conditions, determined by high-index-contrast thin film stacks symmetrically arranged on each side of the tunneling layer, are both band-limited and polarization dependent. The filter is characterized by high out-of-band rejection over a wide range of wavelengths. The blocked (rejected) light is efficiently reflected, and the beam characteristics of...

A tunable resonant tunneling gap for resonant tunneling across the tunneling gap. By adjusting the width of the tunneling gap and adjusting an angle of incidence of light onto the tunneling gap, a pass-band shape and center wavelength may be tuned. The tunneling gap may be an air gap between lenses coated with matching Bragg reflectors. The air gap may be adjusted for example using piezo actuators connecting between the lenses. The angle of incidence may be adjusted for example by rotating...
