I am wondering how can I bond a optical fiber to waveguide grating coupler. Should I use some type of glue? Or should I fix the fiber with a translation stage?

  • $\begingroup$ Can you share a photo, drawing, or specification document of the coupler? $\endgroup$

  • $\begingroup$ @ThePhoton Thank you for your answer. Possible figures could be figure 5 of osapublishing.org/oe/… or figure 18(a) of mdpi.com/2076-3417/8/7/1142. There seems many alternatives but I wonder which might be the most feasible one for beginners. $\endgroup$

  • $\begingroup$ @Cryo Thank you. So I need to UV cure it. $\endgroup$

    $\begingroup$ @Rickyim. This is just one option. I guess you can find other ones, maybe cured by heating. But UV-curing does seem to be popular $\endgroup$
