Patent ID: 6944374

Claim:
A method of manufacturing an optical filter wherein the optical fiber component is characterized by an operating wavelength of a selected wavelength, and wherein the optical filter comprises an optical fiber component attached to a thermal compensation device at first and second fixing points, the method comprising: i. inserting the optical fiber component into the thermal compensation device; ii. applying strain to the optical fiber component; iii. flowing glass solder to attach the optical fiber component to the thermal compensation device at the first and the second fixing points; iv. measuring the operating wavelength of the optical fiber component; v. adjusting the strain applied to the optical fiber component to tune the operating wavelength to the selected wavelength; and vi. allowing the glass solder to solidify; wherein the step of measuring the operating wavelength of the optical fiber component is carried out prior to adjusting the strain applied to the optical fiber component to tune the operating wavelength, and the step of allowing the glass solder to solidify is carried out after adjusting the strain applied to the optical fiber component to tune the operating wavelength.
