•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.
