2 Aug 2015 | Abstract: | We analyze the steady-state transmission of high-momentum (high-$k$)
electromagnetic waves through metal-semiconductor multilayer systems with loss
and gain in the near-infrared (NIR). Using a semi-classical optical gain model
in conjunction with the scattering matrix method (SMM), we study indium gallium
arsenide phosphide (InGaAsP) quantum wells as the active semiconductor, in
combination with the metals, aluminum-doped zinc oxide (AZO) and silver (Ag).
Under moderate external pumping levels, we find that NIR transmission through
Ag/InGaAsP systems may be enhanced by several orders of magnitude relative to
the unpumped case, over a large angular and frequency bandwidth. Conversely,
transmission enhancement through AZO/InGaAsP systems is orders of magnitude
smaller, and has a strong frequency dependence. We discuss the relative
importance of Purcell enhancement on our results and validate analytical
calculations based on the SMM with numerical finite-difference time domain
simulations. | Source: | arXiv, 1508.0179 | Services: | Forum | Review | PDF | Favorites |
