APPARATUS, METHOD, AND COMPUTER PROGRAM PRODUCT FOR CONTROLLING LASER WAVELENGTH STABILITY |
摘要 |
<p>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 in the controlled wavelength range that is generated by the laser when heated by the heater from the second temperature is longer than a short wavelength that is generated by the laser centered on the specific wavelength that operates at the second temperature; and a control circuit configured to turn on the heater.</p> |
