A design of compact DBR resonators (∼ 40 μm-long) integrated in SOI rib waveguide
structure has been demonstrated, exhibiting a resonance bandwidth as low as 40 pm (λr~
1550 nm) with an extinction of∼ 35 dB over a rejection band of∼ 60 nm. The resonance
peak has been thermo-optically tuned over a wide range of wavelength at a rate of~ 95
pm/mW. The device is shown to be effective in ASE noise suppression of an amplified pump
laser.
