The DFB laser includes a separate confinement heterostructure layer positioned between the quantum well active layer and then-type cladding layer. The DFB laser includes an electric-field-distribution-control layer positioned between the separate confinement heterostructure layer and then-type cladding layer and configured by at least two semiconductor layers having band gap energy greater than band gap energy of a barrier layer constituting the quantum well active layer. The DFB laser has a function to select a specific wavelength by returning a specific wavelength in the wavelength-variable laser.

  • Publication number: 20170288367
    Abstract: A circuit conductor is provided on a base. A semiconductor laser is connected to the circuit conductor. Cutout parts on which the circuit conductor is not formed are provided at, for example, the vicinity of the four corners of the base, and a hole is provided at each of the said portions. The holes penetrate the base. Fixing members are inserted through the holes. The fixing members are, for example, male threads. Since the head part of the fixing members is located in the cutout part, the fixing members and the circuit conductor are not in contact with each other. A platform has holes formed at portions corresponding to the holes in the optical unit and female threads formed on the inner surface. The fixing members and the platform are therefore joined. As a result, the optical unit is fixed to the platform.

  • Patent number: 9503774
    Abstract: An information display device includes: a display unit, an information obtaining unit which obtains program-related information related to a video program displayed on a video display device following the video program; and a terminal control unit which causes the display unit to display the program-related information obtained by the information obtaining unit. When the information obtaining unit is unable to obtain first program-related information related to a first video program currently displayed on the video display device following the first video program, the terminal control unit causes the display unit to display (i) second program-related information distributed before the first video program is displayed on the video display device, or (ii) third program-related information related to the second video program displayed before the first video program is displayed on the video display device.

  • Patent number: 9349283
    Abstract: In one aspect, when a user directs a remote controller (13) toward a television set (11), causing the remote controller (13) and the television set (11) to enter the wireless communication region of each other, the remote controller (13) and the television set (11) establish a wireless link to each other. When the user directs the remote controller (13) toward an air conditioner (12), causing the remote controller (13) and the air conditioner (12) to enter the wireless communication region of each other, the remote controller (13) and the air conditioner (12) establish a wireless link to each other. The remote controller (13) and the television set (11) are out of the wireless communication region of each other at this point, and the wireless link between the two is thus disconnected.
