ABSTRACT:
The present invention provides a method (600) and device (200,500) for providing temperature-stable optical feedback for optical packages. The device includes an optical emitter (202,502), a first partially reflective optical element (204, 504), a second partially reflective optical element (206,506), a first optical sensing unit (208,508), a second optical sensing unit (210,510), and a feedback unit (212). The optical emitter (202,502) is responsive to an electrical input current and generates a beam of light (214). The first optical sensing unit (208,508) and the second optical sensing unit (210,510) receive diffracted portions of the beam of light (214) from the first partially reflective optical element (204, 504) and the second partially reflective optical element (206,506) respectively and generate a first feedback signal E1 and a second feedback signal E2. The feedback unit (212) utilizing the first feedback signal E1 and the second feedback signal E2 adjusts the electrical input current to the optical emitter (202,502).
