Double microdisk steers output laser light

A way of providing directional optical output from a microdisk laser has been developed in collaborative efforts by scientists at Northwestern University (Evanston, IL) and the University of California (San Diego, CA). By fabricating a stacked double-disk structure, laser emission at 1.5 µm from the lower disk is coupled to the to¥waveguiding disk. The inclusion of a notch in the to¥disk allows most of the light to be leaked to that point rather than from the entire circular edge of
