  • Very high-energy gamma-ray follow-up program using neutrino triggers from IceCube
  • 2016
  • Ingår i: Journal of Instrumentation. - 1748-0221 .- 1748-0221. ; 11
  • Tidskriftsartikel (refereegranskat)abstract
    • We describe and report the status of a neutrino-triggered program in IceCube that generates real-time alerts for gamma-ray follow-up observations by atmospheric-Cherenkov telescopes (MAGIC and VERITAS). While IceCube is capable of monitoring the whole sky continuously, high-energy gamma-ray telescopes have restricted fields of view and in general are unlikely to be observing a potential neutrino-flaring source at the time such neutrinos are recorded. The use of neutrino-triggered alerts thus aims at increasing the availability of simultaneous multi-messenger data during potential neutrino flaring activity, which can increase the discovery potential and constrain the phenomenological interpretation of the high-energy emission of selected source classes (e. g. blazars). The requirements of a fast and stable online analysis of potential neutrino signals and its operation are presented, along with first results of the program operating between 14 March 2012 and 31 December 2015.

  • Silicon photonic MEMS : Exploiting mechanics at the nanoscale to enhance photonic integrated circuits
  • 2019
  • Ingår i: Optics InfoBase Conference Papers. - Washington, D.C. : OSA - The Optical Society.
  • Konferensbidrag (refereegranskat)abstract
    • With the maturing and the increasing complexity of Silicon Photonics technology, novel avenues are pursued to reduce power consumption and to provide enhanced functionality: exploiting mechanical movement in advanced Silicon Photonic Integrated Circuits provides a promising path to access a strong modulation of the effective index and to low power consumption by employing mechanically stable and thus non-volatile states. In this paper, we will discuss recent achievements in the development of MEMS enabled systems in Silicon Photonics and outline the roadmap towards reconfigurable general Photonic Integrated Circuits.

  • The MORPHIC Project: Enabling large scale programmable photonic circuits using MEMS
  • 2018
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • In MORPHIC, we are enhancing the capabilities of already established silicon photonics platform with low-power and non-volatile MEMS actuators to achieve programmability and re-configurability of the photonic circuits. The combining of high speed silicon photonics, non-volatile MEMS actuation, electronics controlled reconfigurable connectivity and high level design methodologies and programming interface in a package will lead to a complete Field-Programmable Photonic Integrated Circuits (FP-PIC) platform. Ultimately, technology platforms for both generic FP-PIC and Application-Specific Photonic Integrated Circuits (AS-PIC) with possibility of volume manufacturing will be demonstrated.
