Nanoscale displacement sensor

The ability to measure very precise alignments and displacements is a key requirement for many steps in semiconductor fabrication and manufacturing, for example, during lithography or wafer bonding. Using small nanoparticles, exhibiting a Huygens dipole coupled to crossed Photonic crystal … Continue reading

Nanoantennas demonstrating weak superradiance

Dicke superradiance is a phenomenon where multiple closely spaced emitters can enter a collective excited state with a much shorter lifetime than the excited states of the individual emitters. Together with collaborators at the Universities of Rochester, Ottawa, Toronto, British … Continue reading

Flexible metasurface patches for mm-wave applications

In this work, we present a flexible metasurface that operates in the mm-wavelength region. A major problem in modern technology is that many systems, e.g. antennas, are designed for specific functionality. If new functionality is needed, then a new antenna … Continue reading

Flexible epsilon-near-zero metamaterials

Epsilon-near-zero materials promise non-linear optical enhancement, light transport through arbitrary channels, wave-front shaping and control over optical emission. Typically implemented using either naturally occurring effects for example in conductive oxides or through multi-layer stacks all implementations are limited to flat-substrates … Continue reading

Vertical couplers for multi-layer photonic integrated circuits

Similar to microelectronic circuits, future photonic chips will include multiple layers of different materials to integrate functionality in a single circuit. One of the key challenges is to couple light between the different layers. Together with the nanophotonics group at … Continue reading

Flat-band superprism in photonic crystals

One of the key tasks in integrated photonics is the separation or demultiplexing of multiple different wavelength channels that are transported through the same waveguide. One way to separate different wavelength is to use refraction in a prism and the … Continue reading
