摘要： PROBLEM TO BE SOLVED: To solve a problem that the direction of a polarized wave of an ejected laser beam is not settled in a surface-emitting semiconductor laser utilizing a diffraction grating.
SOLUTION: The surface-emitting semiconductor laser device is provided with a lamination structure wherein an active layer 26 is formed between a pair of a lower clad layer 24 and an upper clad layer 28. The diffraction grating 32 is formed on the upper clad layer 28. The diffraction grating 32 is has a bearing range constituted of the diffraction grating 32 in which a distance from a center to the diffraction grating 32 is uniform. Further, the diffraction grating 32 has the other bearing range having a distance (the diffraction grating is not formed, and therefore, the distance is substantially infinity) different from the uniform distance. The bearing range is a region 32a wherein ring opening regions of a plurality of the diffraction gratings 32 coincide along the peripheral direction from the center of the diffraction gratings 32.

摘要： PROBLEM TO BE SOLVED: To improve a responding speed of a III nitride compound semiconductor light-emitting element for optical communication. SOLUTION: In the light-emitting element for the communication using a III nitride compound semiconductor, a light-emitting layer has a quantum well structure, in which the number of well layers is set to an arbitrary number in the range of 1 to 5, and an area of a light-emitting unit of the emitting layer is set at 0.001-0.032 mm 2 . Thus, a high-frequency cut-off frequency becomes 50 MHz or higher, and the high-frequency cut-off frequency is improved 1.7 times as high as that at 30 MHz of conventional elements. A light, having a wavelength range of low transmission loss of a plastic fiber of 450-550 nm, can be emitted from the III nitride compound semiconductor light-emitting element. As a result, a simple LAN (local area network) using the plastic fiber can be constructed at low cost. COPYRIGHT: (C)2004,JPO
