Abstract:
A distributed reflector (DR) laser may include a distributed feedback (DFB) region and a distributed Bragg reflector (DBR). The DFB region may have a length in a range from 30 micrometers (μm) to 100 μm and may include a DFB grating with a first kappa in a range from 100 cm −1  to 150 cm −1 . The DBR region may be coupled end to end with the DFB region and may have a length in a range from 30-300 μm. The DBR region may include a DBR grating with a second kappa in a range from 150 cm −1  to 200 cm −1 . The DR laser may additionally include a lasing mode and a p-p resonance frequency. The lasing mode may be at a long wavelength side of a peak of a DBR reflection profile of the DBR region. The p-p resonance frequency may be less than or equal to 70 GHz.

Claim (Index 19):
A distributed reflector (DR) laser, comprising:\n a distributed feedback (DFB) region and comprising a DFB grating with a first kappa; a distributed Bragg reflector (DBR) region coupled end to end with the DFB region, and comprising a DBR grating with a second kappa; a lasing mode at a long wavelength side of a peak of a DBR reflection profile of the DBR region; wherein the lasing mode changes frequency toward the peak of the DBR reflection profile in response to a change in electrical current in the DFB region; and an external cavity mode within 1 nanometer of the lasing mode.
