20130128341 | Optical Amplifier System and Method - The invention provides a system for use in an optical communication network to reduce noise comprising means for tapping a low noise signal from said network and a phase sensitive amplifier (PSA) for conditioning said tapped signal by means for removing modulation of the tapped signal to allow for phase locking of the tapped signal. A laser source provides phase locked reference signals to generate at least one pump signal, wherein the at least one pump signal provides correct phase alignment for optimum PSA operation. The invention makes use of injection locked and/or phase locked laser sources in conjunction with low power input tap couplers, or post/mid amplification taps to provide the required phase locked reference signals without degrading the input loss or noise. The use of injection/phase locked local lasers suppresses the detrimental impact of the low tapped power or added noise in the generation of the required pump signals. | 05-23-2013 |

20120236302 | NANOSCALE VISOMETER DEVICE - A nano viscometer device suitable for determining the concentration of a solute within a fluid sample preferably includes a hollow core Photonic Crystal Fibre (HC-PCF) acting as a capillary tube having a core and means for filling the capillary tube with a fluid sample. Light is preferably guided light into the HC-PCF and detected exiting the tube. The rate at which the capillary tube is filled with the fluid is optically measured based on the light to determine the viscosity of the fluid to calculate the concentration of a solute. The preferred capillary viscometer is capable of measuring the viscosity of nano-litre quantities of a sample fluid. On one example, the preferred viscometer makes use of HC-PCF for the detection of glucose dissolved in nano water, demonstrating that HC-PCF can be used for continuous monitoring of glucose levels within blood plasma. | 09-20-2012 |
