Abstract
A laser diode package assembly is described. Besides a laser diode, the package assembly has an optical fiber section having an end located to receive the light output from the laser diode. The optical fiber section also has a fiber grating designed to operate as a bandpass filter. The fiber grating inside the package assembly not only narrows the output wavelength from the laser diode, but also increases the lifetime of the laser diode.
