Shaping Nanowire Tapers… With A CO2 Laser Powered Micro-Furnace
•To test a CO2 Laser Powered Micro-Furnace in tapering fibres.
•Stretching heated fibres so that they thin down.
•Pass light in, detect light out, work out optical loss.
•Fibre Optic Cable: “Flexible, optically transparent wire through which light can be transmitted by total internal reflection.”
•Taper: “A section of optical fibre that has a continuously changing outer dimension along its length.”
•Taper’s waist included!
•Nanowire: Optical fibre with diameter on the micron or, ideally, submicron scale.
Why do we care?
•Nanowires transmit some of the light energy OUTSIDE cladding!
•This is called ‘Evanescent Field’.
•Other fibres and crystals can interact with this field.
