Abstract :
We measured the emission decay rates of self-assembled InAs single quantum dots (QDs) embedded in subwavelength-width semiconductor waveguides with and without Au side claddings. The Au claddings increased the decay rate of single QDs by ~2 times, which is consistent with numerical simulations taking account of fabrication imperfection.
