Article that comprises a laser coupled to an optical fiber

摘要

Disclosed is a laser/fiber mount that can advantageously be used in laser transmitter packages for a variety of purposes, including pump laser packages for optically amplified optical fiber transmission systems and fiber-to-the-home systems. Both laser and fiber are attached to the same unitary body, preferably a Si body. An integral heater serves to melt a quantity of solder that serves to bond the fiber to the body after alignment of the fiber to the laser. A relatively thick dielectric layer underneath the heater provides a large thermal impedance, insuring that the temperature of the unitary body is at least 50 degrees C. (preferably 150 degrees C.) less than that of the solder.
