Abstract :
The work has fabricated flip-chip-bondable VCSELs for hybrid integration with atomic clock microsystems. A shallow surface relief in combination with a surface grating are etched in an extra topmost GaAs quarter-wave antiphase layer in the VCSEL structure, which establishes an inverted grating relief
