(Color online) (a) FIB topography and (b) characteristics of , gold nanorod array fabricated on the VCSEL with oxide aperture area.
(Color online) Polarization resolved characteristics with (a) an external polarizer and (b) a Glan-Thompson prism. The arrow in (b) shows the orthogonal polarization suppression ratio of at an injection current of .
(Color online) Single transverse mode lasing spectra of nanorod array integrated VCSEL. The numbers on peaks indicate the injection current in milliamperes. The right arrow shows the side mode suppression ratio of at least throughout the current injection range.
