| 英文摘要 | The present invention provides a light emitting head which has high utilization efficiency of light and facilitates alignment with other heads and which facilitates fabrication, information storage device which provides high volume access to information with such a light emitting head, and composite head manufacturing method suitable to fabricate a composite head having such a light emitting head. The light emitting head includes: a first structure section including a first well propagating section consisting of a low extinction material with substantially negligible attenuation of light, a second well propagating section consisting of another low extinction material with substantially negligible attenuation of light, and whose refractive index is larger than that of the first well propagating section, and a poor propagating section consisting of a material with a propagating characteristics poorer than the second well propagating section; and a second structure section concentrating light on the first structure section. |
