Nanoplasmonic distributed Bragg reflector resonators for monolithic integration on a complementary metal-oxide-semiconductor platform

We present nanoplasmonic Au/SiO2/Si metal-insulator-semiconductor distributed Bragg reflector resonators capable of broadband operation and with the potential for monolithic integration with complementary metal-oxide-semiconductor technology. With a compact device footprint as small as 1.5 μm2 and q...

Zusammenfassung:We present nanoplasmonic Au/SiO2/Si metal-insulator-semiconductor distributed Bragg reflector resonators capable of broadband operation and with the potential for monolithic integration with complementary metal-oxide-semiconductor technology. With a compact device footprint as small as 1.5 μm2 and quality factors as high as 64.4 at λ = 1.545 μm, these resonators have the highest quality factor over device footprint figure of merit yet demonstrated for a silicon nanoplasmonic device. A higher quality factor is shown to be achievable by using smaller gaps in the Bragg reflectors.
