Subwavelength Nanopatch Cavities for
Semiconductor Plasmon Lasers
Christina Manolatou and Farhan Rana
Abstract--We propose and analyze a family of nanoscale cavi-
ties for electrically pumped surface-emitting semiconductor lasers
that use surface plasmons to provide optical mode confinement in
cavities which have dimensions in the 100300-nm range. The pro-
posed laser cavities are in many ways nanoscale optical versions
of micropatch antennas that are commonly used at microwave/RF
frequencies. Surface plasmons are not only used for mode confine-
ment but also for output beam shaping to realize single-lobe far-
field radiation patterns with narrow beam waists from subwave-
length size cavities. We identify the cavity modes with the largest
quality factors and modal gain, and show that in the near-IR wave-
length range (1.01.6 m) cavity losses (including surface plasmon
losses) can be compensated by the strong mode confinement in
the gain region provided by the surface plasmons themselves and
the required material threshold gain values can be smaller than
700 cm 1.
