LIGHT EMITTING DEVICE AND SUPER-LUMINESCENT DIODE HAVING LAYER WITH FIRST, SECOND AND THIRD WAVEGUIDES

摘要

A light emitting device includes a first layer that generates light by an injection current, the first layer is provided with a first optical waveguide extending from a first light emitting section disposed on a first side surface to a first light reflecting section disposed on a second side surface, a second optical waveguide extending from the first light reflecting section to a second light reflecting section disposed on a third side surface, and a third optical waveguide extending from the second light reflecting section to a second light emitting section disposed on the first side surface, and an element of the group II or the group XII is diffused in the first light reflecting section and the second light reflecting section.

1. A light emitting device comprising:
a first layer that generates light by an injection current; and a second layer and a third layer that sandwich the first layer and suppress leakage of the light, wherein the first layer is provided with:
a first optical waveguide extending from a first light emitting section disposed on a first side surface of the first layer to a first light reflecting section disposed on a second side surface of the first layer,a second optical waveguide is extending from the first light reflecting section to a second light reflecting section disposed on a third side surface of the first layer, anda third optical waveguide is extending from the second light reflecting section to a second light emitting section disposed on the first side surface, and an element from one of group II or group XII of the periodic table of elements is diffused in the first light reflecting section and the second light reflecting section.
