Zusammenfassung: | The utility model relates to the technical field of light receiving TO CAN, in particular to a miniaturized optical receiving assembly with a heating function, which comprises a TO base, a heating part, a PD chip, a gasket and a TO tube cap, the PD chip is fixed on the gasket, the gasket is fixed on the heating component, and the heating component is installed on the TO base; the PD chip and the heating component are electrically connected with a pin of the TO base in a gold wire bonding manner; and the TO tube cap and the TO base are fixedly packaged. According to the utility model, the problem that the low-temperature responsivity of the conventional PD chip is sharply reduced near 1650nm is solved, so that the conventional PD chip can also be applied to gas detection near 1654nm, the cost of an optical receiver is greatly reduced, and the large-scale commercial application of a laser gas sensing technology is facilitated.
