  • Abstract
    In this work, a whispering gallery mode (WGM) microdisk resonator based on Ge1-xSnx grown by molecular beam epitaxy (MBE) was fabricated and characterized. Various process conditions and different Sn contents (4% and 1%) were explored to confirm the feasibility of Ge1-xSnx for microcavity device operation. Optical modes with wavelengths in the infrared (IR) range beyond 1550 nm were successfully confined in the devices fabricated with different diameters, and free-spectral ranges (FSRs) near 20 nm were obtained.
