| 英文摘要 | A living body measuring instrument having a sub-mount (4) on which plural light-emitting devices (1,2,3) oscillating at different wavelengths are mounted in proximity, one optical output monitoring device (9) that detects the optical outputs of these light-emitting devices, wherein said light emitting devices and said monitoring device are mounted on the same heat sink and are housed in one can-package, a light-receiving device that detects a signal from a living body, and a circuit that separates the optical output signals from the light-emitting devices, wherein at least one light-emitting device has a light-emitting layer including a In1-xGaxAsyP1-y quantum well layer and a barrier layer on a GaAs substrate, the strain ε satisfies 0.4%≤ε≤4%, wherein y in the composition satisfies 0.10≤y≤0.45, and the wavelength of the emitted light is from 700 nm to 760 nm. |
