Abstract

A fully post-growth integrated chirped Bragg grating (CBG) in III-V material is presented based on a tapered waveguide geometry. The deeply etched structure provides the high coupling coefficient required in CBG devices without recourse to overgrowth fabrication techniques and the taper method allows for arbitrary chirp functions to be implemented. A 5-nm stopband with 0.0335 ps/nm dispersion is demonstrated and DFB lasers based on the CBG structure are presented
