    摘要： An embodiment of the inventive concept includes an optical signal generating circuit, a controlling circuit, a waveform shaping circuit, and an output circuit. The optical signal generating circuit generates a first optical signal including pulses. The controlling circuit generates a control signal indicating a first pulse to be attenuated in magnitude among the pulses. The waveform shaping circuit attenuates a magnitude of the first pulse based on the control signal and the first optical signal, and generates a second optical signal including pulses corresponding to the pulses included in the first optical signal and the first pulse having the attenuated magnitude. The output circuit outputs an electric signal of bands corresponding to differences between frequencies of the pulses included in the second optical signal based on the second optical signal. A band corresponding to the first pulse among the bands of the electric signal is adjusted as the magnitude of the first pulse is attenuated.

    摘要： Provided is a method of fabricating an organic light emitting device that may form a light scattering layer having an irregular random structure at a low temperature. The method includes providing a substrate coated with a precursor layer; sequentially forming a metal layer and an organic layer on the precursor layer; performing a heat treatment of the organic layer to form an organic mask from the organic layer; patterning the metal layer by using the organic mask to form a metal mask; patterning the precursor layer by using the metal mask to form a light scattering layer having an irregular random structure; removing the metal mask and the organic mask; and sequentially stacking a planarization layer, a first electrode, an organic light emitting layer, a second electrode, and a passivation layer on the light scattering layer.
