摘要： PROBLEM TO BE SOLVED: To provide an optical module or the like which enables temperature control of an optical element with a simple structure while achieving low power consumption.SOLUTION: In an optical module 10, an optical element 11, where a DFB-LD and an optical modulator are integrated, is mounted on a first cooling part 13, and a wavelength monitor 14 is mounted on a second cooling part 15. When a transmission line 16 transmitting a modulation signal is disposed from a modulation signal input part 122 of a package 12 to the optical element 11, the transmission line 16 is placed in contact with the second cooling part 15 in an area between the modulation signal input part 122 and a position that the transmission line 16 contacts with a surface of the first cooling part 13 on which the optical element 11 is mounted. The optical module 10 having the structure reduces the sum of power consumption of the first cooling part 13 and the second cooling part 15, compared to a case where the transmission line 16 does not contact with the second cooling part 15.

摘要： PROBLEM TO BE SOLVED: To provide an optical multiplexer/demultiplexer enabling low loss and downsizing.SOLUTION: Input light beams emitted by light-emitting parts 10a-10d are inputted into transmission waveguides 210a-210d. Between the transmission waveguides, resonance waveguides 230a-230d are arranged in parallel with the transmission waveguides. Distances da1, da2 between the transmission waveguide and the resonance waveguide approximate to each other so as to form migration parts 240a-240d for migrating light beams of a predetermined migration wavelength component. Each resonance waveguide has a perfect coupling length of a migration wavelength. Consequently, the light beams inputted from the light-emitting parts 10a-10d are multiplexed and outputted from an output waveguide 210c.

摘要： PROBLEM TO BE SOLVED: To make an interval of monitor wavelengths narrow without enlarging a device.SOLUTION: A wavelength monitor 10 has a light source 30, a filter 50, and a detector 60. The filter 50 has periodic permeability to a wavelength of light. Light emitted from the light source 30 and permeating through the filter 50 has strength according to the wavelength of the light. The detector 60 detects the light permeating through the filter 50 on plural light reception faces arranged at different positions. Thereby, the detector 60 can detect space distribution of the light permeating through the filter 50. The space distribution depends on the wavelength of the light, and indicates a characteristic different from the permeability of the filter 50. Accordingly, the plural light reception faces are appropriately arranged to detect the space distribution of the light, and therefore, an interval of monitor wavelengths can be made narrow without enlarging a device.
