A new concept for the fabrication of integrated microring
resonators, requiring only one single epitaxial growth and two single-side
lithographic steps, is proposed in what is the simplest fabrication scheme
for vertical microrings published to date. The approach is based on two
vertically stacked phase matched core layers. The effect of bus waveguide,
coupling region and ring structure parameters is theoretically analyzed.
Numerical calculations predict high performance devices with quality
factors of over 10000. The scheme can feature both active and passive
regions, allowing the fabrication of microring lasers.
