Easy method to transfer optical devices from fabrication wafer to the tip of an optical fiber

What is it about?

The paper describes an easy and scalable method to transfer optical devices fabricated on a wafer in large quantities to the cleaved end of an optical fiber. The method is applied to a 2D photonic crystal membrane device and its performances as a temperature and refractive index sensor are tested.

Why is it important?

The proposed transfer method allows for a reproducible transfer of independently designed optical devices. Because the devices are fabricated on a wafer they can be produced in large quantities and there is no machining of the fiber involved. Because the method relies on designed breaking points the transfer can happen reliably at room conditions within a few minutes without the need for expensive machinery.
