Selective tuning of high-Q silicon photonic crystal nanocavities via laser-assisted local oxidation
Charlton J. Chen, Jiangjun Zheng, Tingyi Gu +5
We examine the cavity resonance tuning of high-Q silicon photonic crystal heterostructures by localized laser-assisted thermal oxidation using a 532 nm continuous wave laser focuse…
Deterministic tuning of slow-light in photonic-crystal waveguides through the C and L bands by atomic layer deposition
Charlton J. Chen, Chad A. Husko, Inanc Meric +5
We demonstrate digital tuning of the slow-light regime in silicon photonic-crystal waveguides by performing atomic layer deposition of hafnium oxide. The high group-index regime wa…
Temperature-tuning of near-infrared monodisperse quantum dot solids at 1.5 um for controllable Forster energy transfer
Ranojoy Bose, James F. McMillan, Jie Gao +5
We present the first time-resolved cryogenic observations of Forster energy transfer in large, monodisperse lead sulphide quantum dots with ground state transitions near 1.5 um (0.…
Observations of interior whispering gallery modes in asymmetric optical resonators with rational caustics
Jie Gao, Pascal Heider, Charlton J. Chen +3
We propose asymmetric resonant cavities with rational caustics and experimentally demonstrate interior whispering gallery modes in monolithic silicon mesoscopic microcavities. Thes…
Digital resonance tuning of high-Q/Vm silicon photonic crystal nanocavities by atomic layer deposition
Xiaodong Yang, Charlton J. Chen, Chad A. Husko +1
We propose and demonstrate the digital resonance tuning of high-Q/Vm silicon photonic crystal nanocavities using a self-limiting atomic layer deposition technique. Control of reson…
