Abstract
Disclosed is a submount integrated photodiode package with an improved metal layer configuration and laser diode package using the same. In particular, a unitary laser diode of the invention provides a light receiving area overlying a semiconductor substrate to correspond to a radiation area of light emitted from a laser diode so as to reduce chip size in respect to a conventional one while maintaining a monitoring current identical to the conventional one as well as improve heat-radiating features. The invention provides a unitary laser diode package which comprises a light receiving area overlying a semiconductor substrate and having the same configuration as a radiation area of emission light from the laser diode and a metal layer adjacent to the light receiving area.
