Abstract: A laser light source includes: a resonance unit with a light emitter; and an optical negative feedback unit. The resonance unit includes: a first waveguide; a first reflector to input the reflected light to the first waveguide; a second waveguide; a second reflector connected to the second waveguide; and a ring resonator between the first waveguide and the second waveguide. The light from the first reflector is blocked from the ring resonator and partially transmitted to a first end of the first waveguide opposite to a second end connected to the light emitter and the first reflector. The optical negative feedback unit includes: a third waveguide to which the light transmitted to the first end of the first waveguide is inputted; and a third reflector connected to the third waveguide. The light from the third reflector is inputted to the first waveguide via the third waveguide.

Abstract: It is a CNT device (1) (carbon-metal structure) equipped with a carbon nanotube layer (2) (CNT layer 2; same hereafter) on a metal pedestal (4). The metal pedestal (4) is brazed to the CNT layer (2) with a brazing material layer (3) interposed therebetween. When manufacturing the CNT device (1), firstly, the CNT layer (2) is formed on a heat-resistant textured substrate (6). Next, the metal pedestal (4) is brazed to the CNT layer (2) that is on the heat-resistant textured substrate (6) with the brazing material layer (3) interposed therebetween. Then, the metal pedestal (4) (and the CNT layer 2) is peeled off the heat-resistant textured substrate (6) to transfer the CNT layer (2) from the heat-resistant textured substrate (6) to the metal pedestal (4).

Abstract: A bonding method is capable of realizing high bonding strength and connection reliability even at a connection part in a high temperature area by means of simple operation low temperature bonding. The method includes a first step wherein, on at least one of the bonded surfaces of two materials to be bonded having a smooth surface, a thin film of noble metal with a volume diffusion coefficient greater than that of the base metal of the material to be bonded is formed using an atomic layer deposition method at a vacuum of 1.0 Pa or higher, a second step wherein a laminate is formed by overlapping the two materials to be bonded so that the bonded surfaces of the two materials are connected through the thin film, and a third step wherein the two materials to be bonded are bonded by holding the laminate at a predetermined temperature.
