Opto-Vlsi-Based Tunable Linear-Cavity Fibre Laser, David Michel, Feng Xiao, Kamal Alameh
Research outputs pre 2011
A novel approach using an Opto-VLSI processor to achieve a tunable fibre laser is presented. The Opto-VLSI based fibre laser is able to tune wavelengths and maintain a high Side-Mode Suppression Ratio (SMSR) even when the output optical power is low. Experimental results show a continuously tunable fibre laser source with a tuning range as high as 30 nm and a SMSR exceeding 30 dB.
Effect Of A Polywell Geometry On A Cmos Photodiode Array, Paul V. Jansz, Steven Hinckley, Graham Wild
Effect Of A Polywell Geometry On A Cmos Photodiode Array, Paul V. Jansz, Steven Hinckley, Graham Wild
Research outputs pre 2011
The effect of a polywell geometry hybridized with a stacked gradient poly-homojunction architecture, on the response of a CMOs compatible photodiode array was simulated. Crosstalk and sensitivity improved compared to the polywell geometry alone, for both back and front illumination

Research outputs pre 2011
Since the 1960's, Magneto-optic (MO) garnet materials have been studied extensively. These materials can possess world-record MO performance characteristics in terms of Faraday rotation and optical quality. Among the rear-earth-doped garnets, the Bi-substituted iron garnet is the best candidate for use as a functional material in different integrated-optics, imaging/image processing applications and also in forward-looking applications e.g. the design of metamaterials with non-reciprocal properties. We have established a set of technologies for fabricating ferrimagnetic garnet films of type (BiDy)3(FeGa)5O12 and also garnet-oxide nanocomposite (BiDy)3(FeGa)5O12 : Bi2O3 layers possessing record-high MO quality across the visible spectral range using RF-magnetron sputtering and …

Simulation Of A Hybrid Polywell And Stacked Gradient Poly-Homojunction Cmos Photodiode, Paul V. Jansz, Steven Hinckley
Research outputs pre 2011
In this paper, we have simulated the performance of a photodiode array that has multiple wells per pixel as well as a stacked-gradient poly-homojunction (StaG) geometry. The pixel response resolution was improved when the first StaG epilayer was within 2 μm of the space charge region (SCR).
