  • Surface-Acoustic-Wave Modulation of a Silicon-on-Insulator Defect Bragg Grating
    Conference on Lasers and Electro-Optics, 2020
    Co-Authors: Dvir Munk, Mirit Hen, Moshe Katzman, Maayan Priel, Avi Zadok
    Abstract:

    A surface acoustic wave modulator is implemented in standard silicon-on-insulator. Acoustic waves are stimulated by absorption of pump light in metallic patterns and thermo-Elastic Expansion, and modulate probe light in a defect waveguide grating cavity.

  • Surface acoustic wave photonic devices in silicon on insulator
    Nature Communications, 2019
    Co-Authors: Dvir Munk, Mirit Hen, Moshe Feldberg, Tali Sharabani, Arik Bergman, M. Priel, Shahar Levy, Moshe Katzman, Avi Zadok
    Abstract:

    Opto-mechanical interactions in planar photonic integrated circuits draw great interest in basic research and applications. However, opto-mechanics is practically absent in the most technologically significant photonics platform: silicon on insulator. Previous demonstrations required the under-etching and suspension of silicon structures. Here we present surface acoustic wave-photonic devices in silicon on insulator, up to 8 GHz frequency. Surface waves are launched through absorption of modulated pump light in metallic gratings and thermo-Elastic Expansion. The surface waves are detected through photo-Elastic modulation of an optical probe in standard race-track resonators. Devices do not involve piezo-electric actuation, suspension of waveguides or hybrid material integration. Wavelength conversion of incident microwave signals and acoustic true time delays up to 40 ns are demonstrated on-chip. Lastly, discrete-time microwave-photonic filters with up to six taps and 20 MHz-wide passbands are realized using acoustic delays. The concept is suitable for integrated microwave-photonics signal processing.The authors implement surface acoustic waves on the silicon photonics platform by exciting a metallic grating with modulated pump light to enable microwave-photonic devices without the need for piezo-electric actuation, complex suspensions or hybrid materials.

  • strain induced tunable wavelength filters based on flexible polymer waveguide bragg reflector
    Optics Express, 2008
    Co-Authors: Mincheol Oh
    Abstract:

    A tunable wavelength filter is demonstrated by imposing a strain on a polymeric Bragg reflection waveguide fabricated on a flexible substrate. The highly Elastic property of flexible polymer device enables much wider tuning than the silica fiber. To produce a uniform grating pattern on a flexible plastic substrate, a post lift-off process along with an absorbing layer is incorporated. The flexible Bragg reflector shows narrow bandwidth, which is convincing the uniformity of the grating structure fabricated on plastic film. By stretching the flexible polymer device, the Bragg reflection wavelength is tuned continuously up to 45 nm for the maximum strain of 31,690 μe, which is determined by the Elastic Expansion limit of waveguide polymer. From the linear wavelength shift proportional to the strain, the photoElastic coefficient of the ZPU polymer is found.
