Researching the Effects of the Presence and Absence of Ionizing Radiation - The REPAIR Project in SNOLAB

Considerable attention has been given to understanding the biological effects of low-dose ionizing radiation exposure at levels slightly above background. However, relatively few studies have been performed to examine the inverse, where natural background radiation is removed.

Yoshi Arita - Photopolymerisation with structured light: new directions in direct laser writing

Direct laser writing (DLW) by two-photon polymerisation is a well-established technique for printing three-dimensional structures with a sub-micrometre resolution by scanning a tightly focused laser beam along a predefined path [1].

Development of Bi/Er co-doped optical fibers with ultra-broadband near infrared luminescence

To improve capacity of photonic networks based on wavelength division multiplexing (WDM), Bi/Er co-doped silica optical fibers (BEDFs) have been proposed and developed for wideband and flat-gain fiber amplifiers operating the whole or the Er-doped fibers uncovered spectral region of 1200 nm to 1700 nm. Ultrabroadband luminescence has been demonstrated in BEDFs fabricated by modified chemical vapor deposition (MCVD) and in-situ doping techniques, and by 3D printed preform. Several novel and sophisticated techniques have been developed for the fabrication and characterization of the BEDFs. For controlling the performance of BEDFs, post-treatment processes using high temperature and laser light have been introduced.

International Year of Glass – research at IPAS on glass science, technology and art

The seminar will first give an overview on glass research at IPAS, highlighting the intricate connection between glass science and technology and even art. One example, and possibly the most famous example, is gold ruby glass, where the intriguing deep red colour is produced by gold nanoparticles. Glass art using gold ruby type glasses has been made for over 2000 years, but only 100 years ago, the scientific discovery of gold nanoparticles as the source of the colour was achieved. The fascination of the science underlying gold nanoparticles in glass is still lively today. Another, recent example of the fine line between glass science and art is the invention and development of glass doped with diamond nanoparticles for quantum sensing applications. This research inspired an artist to create a new type of glass art, and vice versa the glass artist’s method of incorporating nanocrystal in glass inspired glass scientists to advance their diamond-doped glass based quantum sensor.
