ABSTRACT:
A technique for increasing the number of manufactured laser transmitters which meet a predetermined wavelength specification is disclosed. Semiconductor lasers which exhibit a relationship between operating temperature and wavelength can be tuned by adjusting the operating temperature to ensure that the transmitter's operating wavelength will fall within the system-specified limits.
