Title:
LIGHT-EMITTING DEVICE AND HOLOGRAM REPRODUCER EMPLOYING THE LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/020581
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a light-emitting device in which variation in height
of respective light-emitting points of a plurality of light-emitting elements
can, especially, be reduced more appropriately and easily than conventional
ones, and to provide a hologram reproducer employing such a light-emitting device.
[MEANS FOR SOLVING PROBLEMS] The light-emitting device comprises a plurality
of surface emission lasers (12, 13), and a supporting plate (50) for supporting
each surface emission laser (12, 13) from the side of element surface (12b, 13b)
where a light-emitting point (12a1, 13a1) appears. The surface (50a) of the
supporting plate (50) facing the element surfaces (12b, 13b) is formed to have
the same plane, and each element surface (12b, 13b) of the plurality of surface
emission lasers (12, 13) is supported under the same plane (50a). Consequently,
even when the thicknesses of the surface emission lasers (12, 13) are different,
variation in height of respective light emitting points (12a1, 13a1) of the plurality
of surface emission lasers (12, 13) can be reduced more appropriately and easily
than conventional ones.
