摘要
A method for compensating a center wavelength of optical transmission of a planar lightwave circuit includes heating the planar lightwave circuit from a first set temperature to a second set temperature. The first set temperature is at least approximately a room temperature and at most approximately 500° C. The second set temperature is at least approximately 500° C. and at most approximately 900° C. The planar lightwave circuit is maintained at the second set temperature for a predetermined retention time. The planar lightwave circuit is cooled from the second set temperature to a third set temperature. The third set temperature is at least approximately a room temperature and at most approximately 500° C.
