Room temperature exciton-polariton resonant reflection and suppressed absorption in periodic systems of InGaN quantum wells
AS Bolshakov, VV Chaldyshev, EE Zavarin… - Journal of Applied …, 2017 - pubs.aip.org
We studied the optical properties of periodic InGaN/GaN multiple quantum well systems with
different numbers of periods. A resonant increase in the optical reflection and simultaneous
suppression of the optical absorption have been revealed experimentally at room
temperature when the Bragg and exciton resonances were tuned to each other. Numerical
modeling with a single set of parameters gave a quantitatively accurate fit of the
experimental reflection and transmission spectra in a wide wavelength range and various …
