What is it about?
Mode mismatch is an important source of losses when connecting optical waveguides. We present an approach to realize mode converters that minimize this loss, by printing these mode converters directly on the facet of optical fibers.

Why is it important?
To enable wide deployment of photonic integrated circuits, a robust and high-efficiency interface with the outside world is required. In practice, that often boils down to a fiber-to-chip connection. Using our mode conversion tapers, this connection can be made with very high efficiency while allowing physical contact and therefore robust fiber to chip attachment.
Perspectives
We believe that our contribution will boost the wide deployment of photonic integrated circuits.
