Enabling photonic technologies for seeing-limited telescopes: Fabrication of integrated photonic lanterns on a chip

Spaleniak, Izabela; Jovanovic, Nemanja; Gross, Simon; Lawrence, J; Withford, Michael; Ireland, Michael


In this paper we present theoretical and laboratory results on integrated directly-written photonic lanterns with varying taper lengths. These lanterns convert seeing-limited light into multiple diffraction limited signals, in other words, a multimode signal into multiple single-mode signals. We investigated 19-channel structures which were written within a 30-mm-long glass block and designed to operate at 1550 nm. A single structure consisted of a multimode waveguide which transitioned into an...[Show more]
