LIGHT EMITTING DEVICE, RANGING DEVICE AND MOVABLE OBJECT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18507189 titled 'LIGHT EMITTING DEVICE, RANGING DEVICE AND MOVABLE OBJECT
Simplified Explanation
The light emitting device described in the patent application includes a semiconductor light emitting element with a first reflector, a resonator spacer with an active layer, and a second reflector stacked in that order over a semiconductor substrate. A saturable absorption layer is positioned between the semiconductor substrate and the second reflector. The device is designed to emit light with a profile that reaches a maximum peak value and then stabilizes at a predetermined light intensity.

Original Abstract Submitted
The light emitting device includes a semiconductor light emitting element including a first reflector, a resonator spacer including an active layer, and a second reflector stacked in this order over a semiconductor substrate. The semiconductor light emitting element includes a saturable absorption layer provided between the semiconductor substrate and the second reflector. The semiconductor light emitting element is configured to emit light having a profile that has a maximum peak value and converges to a stable value of a predetermined light intensity after the maximum peak value.
