A packaged optical comb source is demonstrated. A low‐linewidth optical comb source is designed and fabricated. The device is packaged in a seven‐pin high‐speed butterfly package with an subminiature version A (SMA) connector for RF modulation and fibre pigtail. Fibre coupling efficiency is estimated at 43%. The packaged comb source is shown to have a linewidth of 300 kHz for the comb line set when modulated at 4 GHz, with eight comb lines within 3 dB of each other. The prototype packaged comb source has applications in high bandwidth telecommunications.
