Compact chip-scale filter based on curved waveguide Bragg gratings (2010)
Journal Article
Zamek, S., Tan, D., Khajavikhan, M., Ayache, M., Nezhad, M., & Fainman, Y. (2010). Compact chip-scale filter based on curved waveguide Bragg gratings. Optics Letters, 35(20), 3477-3479. https://doi.org/10.1364/OL.35.003477

We propose a method for miniaturization of filters based on curved waveguide Bragg gratings, so that long structures can be packed into a small area on a chip. This eliminates the stitching errors introduced in the fabrication process, which compromi... Read More about Compact chip-scale filter based on curved waveguide Bragg gratings.

Curved waveguide Bragg gratings on a chip (2010)
Presentation / Conference Contribution

We demonstrate curved waveguide Bragg gratings on an SOI chip. Our approach allows long Bragg gratings to be fabricated on an extremely small area, avoiding write-field stitching errors, typically introduced in the fabrication process.

Measurement of the optical properties of gold at cryogenic temperatures (2010)
Presentation / Conference Contribution

Optical constants of gold are measured at cryogenic temperatures. The imaginary part of epsilon exhibits a drop at longer wavelengths. This directly demonstrates that performance of metal-based optical devices can be improved by cryogenic cooling.

Polarization weighting of Fano-type transmission through bi-dimensional metallic gratings (2010)
Journal Article

We demonstrate an approach allowing isolating effects of surface plasmon polariton mediated resonant transmission in a periodic grating by means of polarization rotation. The grating comprises a square array of cylindrical holes in an optically thick... Read More about Polarization weighting of Fano-type transmission through bi-dimensional metallic gratings.

A wavelength selective add/drop filter based on coupled vertical gratings is proposed for applications in wavelength division multiplexing on silicon. We demonstrate tailoring of device bandwidth and channel location.

Room-temperature subwavelength metallo-dielectric lasers (2010)
Journal Article

We demonstrate room-temperature pulsed laser emission from optically pumped metallo-dielectric cavities that are smaller than their emission wavelength in all three dimensions. The cavity consists of an aluminium/silica bi-layer shield surrounding an... Read More about Room-temperature subwavelength metallo-dielectric lasers.

Coupled vertical gratings on silicon for applications in wavelength division multiplexing (2010)
Presentation / Conference Contribution

An add/drop filter based on coupled vertical gratings is presented on silicon. We analyze the device theoretically and experimentally and show that the concept is easily extended to multi-channel add/drop filters. We demonstrate tunability of the dev...
