Abstract: Chip-integrated chirped or apodized Bragg gratings (CBGs) are key components for on-chip dispersion compensation. They are increasingly sought after for applications such as dispersion compensation for telecommunications, integrated chirped pulse amplifiers [1], mode-locked lasers [2], and ultrashort pulse soliton generation [3] on a silicon chip. However, maintaining flat group-delay dispersion (GDD) over a large bandwidth without strong ripples is challenging. These ripples typically arise from imperfect apodization profiles, and reflections at the grating boundaries, which can introduce phase inconsistencies and disrupt the desired dispersion profile.
