Measurement of Polarisation Dependent Responsivity of Optical Fibre Power Meters and Optical Spectrum Analysers
D J Ives, National Physical Laboratory UK. ([email protected]) Abstract Many of the sources used in optical fibre systems are highly polarised and thus for highly accurate power measurements the polarisation dependent response (PDR) of the power meter becomes an important parameter. The use of Optical Spectrum Analysers (OSA) to test components and measure the relative powers in WDM systems ...
متن کاملIndependent polarisation control of multiple optical traps.
We present a system which uses a single spatial light modulator to control the spin angular momentum of multiple optical traps. These traps may be independently controlled both in terms of spatial location and in terms of their spin angular momentum content. The system relies on a spatial light modulator used in a "split-screen" configuration to generate beams of orthogonal polarisation states ...
متن کاملFabrication, polarisation and wavelength insensitive optical switch/attenuator based on adiabatic mode multiplexer
Experimental results of an adiabatic mode multiplexer (AMM) based novel 2 2 optical switch/variable optical attenuator that consists of a symmetric Y-branch interferometer (mode converter) and adiabatic mode multiplexer/demultiplexer pair are presented. It is shown that both normally cross and bar designs have identical optical performance. Extinction ratio without thermal activation is wavelen...
متن کاملSingle-polarisation mode in air-core holey fibre
An air-core holey fibre design that supports a single-polarisation circularly symmetric mode is presented. The mechanism that isolates the single polarisation, the advantages of the design and fabrication efforts to date will be discussed.
متن کاملPolarisation Signals
Humans are fascinated by the colour vision, colour signals and ‘dress codes’ of other animals as we can see colour. This property of light may be useful for increasing the contrast of objects during foraging, defence, camouflage and sexual communication. New research, largely from the last decade, now suggests that polarisation is a quality of light also used in signalling and may contain infor...
