Subminiature package external cavity laser

A packaged subminiature external cavity laser with a linewidth of <70 KHz has been developed. The package has outside dimensions of 45 X 20 X 15 mm and is designed with a 10 mm cavity making it capable of direct modulation up to 2.4 Gbit/s. The wavelength is selected during manufacture to within the range 1510-1560 nm with an accuracy of 0.05 nm.
