Photoluminescence from silicon dioxide photonic crystal cavities with embedded silicon nanocrystals

Journal Article (Journal Article)

One-dimensional nanobeam photonic crystal cavities are fabricated in silicon dioxide with silicon nanocrystals. Quality factors of over 9× 103 are found in experiment, matching theoretical predictions, with mode volumes of 1.5 ( λ/n ) 3. Photoluminescence from the cavity modes is observed in the visible wavelength range 600-820 nm. Studies of the lossy characteristics of the cavities are conducted at varying temperatures and pump powers. Free carrier absorption effects are found to be significant at pump powers as low as a few hundred nanowatts. © 2010 The American Physical Society.
