Abstract: Provided is a light-emitting device including an organic light-emitting element and a control unit that controls the organic light-emitting element. The organic light-emitting element includes a first electrode, a second electrode, and an organic light-emitting layer which is disposed between the first electrode and the second electrode and in which separation of charges occurs due to incidence of excited light. The control unit changes a potential difference between the first electrode and the second electrode so that recoupling of the charges occurs, in a second period after passage of a delay period from a first period in which the excited light is incident to the organic light-emitting layer.

Abstract: A quantum cascade detector includes a semiconductor substrate, and an active layer formed by laminating unit laminate structures each having an absorption region with a first barrier layer to a second well layer and a transport region with a third barrier layer to an n-th well layer. A second absorption well layer has a layer thickness ½ or less of that of a first absorption well layer thickest in one period, and a coupling barrier layer has a layer thickness smaller than that of an exit barrier layer thickest in one period. The unit laminate structure has a detection lower level arising from a ground level in the first well layer, a detection upper level generated by coupling an excitation level in the first well layer and a ground level in the second well layer, and a transport level structure for electrons.
