An apparatus includes a laser that generates a predetermined wavelength when the laser operates at room temperature the predetermined , wavelength being offset from a specific wavelength. The laser has a controlled wavelength range due to a wavelength drift the wavelength range having a , first wavelength as the upper boundary and a second wavelength as the lower boundary, the first wavelength is generated when the laser operates at a first temperature of an ambient and the second wavelength is generated when the laser operates at a predetermined temperature higher than a second temperature of the ambient. The apparatus includes a heater that heats the laser such that a , wavelength …
