Abstract:
A semiconductor laser diode package, comprising:a can having a front surface and a back surface parallel to each other;an angled-faceted laser diode having:rectangular top and bottom surfaces, rectangular left and right surfaces, and rectangular front surface and back surface, and an angled-faceted waveguide between said left and right surfaces and normal to said top and bottom surfaces;a sub-mount pedestal for mounting said angled-faceted laser diode at an angle oblique to the front surface and back surface of said can; anda window in the front surface of said can for light beam emitted from the front surface of said angled-faceted laser diode to pass through; anda photo diode mounted at the back of said top surface of said sub-mount pedestal for sensing the light beam emitted from the back surface of said angled-faceted laser diode.
