Title:
集積型光モジュールの光軸調整方法、製造方法、および光軸調整装置
Document Type and Number:
Japanese Patent JP6639696
Kind Code:
B2
Abstract:
An optical axis adjustment method for an integrated optical module includes: measuring output currents by changing a wavelength of a light beam incident on a package; detecting, with first and second light receiving elements, light beams resulted from demultiplexing the incident light beam with first and second filters; detecting center wavelengths of a first light beam and a second light beam based on a change in the output currents in response to a change in the wavelength of the incident light beam; comparing the center wavelengths of the first light beam and the second light beam with design transmission wavelengths of the first filter and the second filter, and defining respective differences as a first wavelength deviation and a second wavelength deviation; and adjusting a position of the optical demultiplexer to make a total sum of the first wavelength deviation and the second wavelength deviation small.
