Shaping Nanowire Tapers… With A CO2 Laser Powered Micro-Furnace

Aim:

•To test a CO2 Laser Powered Micro-Furnace in tapering fibres.

Method:

•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.
