Silicon photonics, the use of light to transmit and process information, has become increasingly popular over the last few years due to its high data transmission rates and compatibility with existing integrated…
One of the exciting application areas for optical metasurfaces is holography. Through a clever arrangement of meta-atoms we use…
Epsilon-near-zero (ENZ) materials are materials that have a spectral region where the permittivity is below zero. This leads to…
Electromagnetically induced transparency (EIT) uses an optical control beam to induce a narrow transparency window in a normally opaque…
As part of the nanofab spin-off from the Photonics online meetup (POM) Dr Schulz gave a short tutorial on how to make a good plasmonic metasurface. The recorded presentation is now available as part of the “Flash Talk”…
The time-bandwidth relation that states that the longer a resonator stores energy, the narrower the bandwidth of supported frequencies and it is an intrinsic limitation to conventional resonators. However, this…
Photonic crystal devices have big potential for nonlinear optics, as they can confine light both spatially and temporally. However, a large number of nonlinear optical processes can occur in these systems, making it…
