Observation of a localized flat-band state in a photonic Lieb lattice
Sebabrata Mukherjee, Alexander Spracklen, Debaditya Choudhury +4
We show experimentally how a non-diffracting state can be excited in a photonic Lieb lattice. This lattice supports three energy bands, including a perfectly flat middle band, whic…
Ultrafast laser inscription of mid-IR directional couplers for stellar interferometry
Alexander Arriola, Sebabrata Mukherjee, Debaditya Choudhury +2
We report the ultrafast laser fabrication and mid-IR characterization (3.39 microns) of four-port evanescent field directional couplers. The couplers were fabricated in a commercia…
Photonic spatial reformatting of stellar light for diffraction-limited spectroscopy
Robert J. Harris, David G. MacLachlan, Debaditya Choudhury +6
The spectral resolution of a dispersive spectrograph is dependent on the width of the entrance slit. This means that astronomical spectrographs trade-off throughput with spectral r…
