title: On-chip, planar integration of Er doped silicon-rich silicon nitride microdisk with SU-8 waveguide with sub-micron gap control.
abstract: On-chip, planar integration of Er-doped Silicon-rich silicon nitride microdisks with SU-8 waveguide and polymer cladding is achieved. The lack of high temperature or etching processes allows back-end integration without any optical damage to the microcavity resonator. The maximum measured Q-factor at 1475.5 nm was 13,000, corresponding to calculated intrinsic resonator Q-factor of 25,000 that is limited by process-related roughness.
