The ART-based DBRs have reflectivity spectra comparable to those grown on bulk GaAs substrates.}, URL = {http://www.mina.ubc.ca/files/Abstract ISTDM 2010 Lin_v5.pdf}, author = {Yiheng Lin and Wei Shi and Jizhong Li and Ting-Chang Chang and Ji-Soo Park and Jennifer Hydrick and Zigang Duan and Mark Greenberg and James Fiorenza and Lukas Chrostowski and Guangrui Xia} }
