Patent ID: 11004893

Abstract:
A photonic integrated device is provided, includes a substrate, a two-dimensional material unit and semiconductor light-emitting units located at both sides thereof are disposed on the substrate; the two-dimensional material unit is provided with a luminescent two-dimensional material of which a luminous band is longer than that of the semiconductor light-emitting unit, and the semiconductor light-emitting unit provides a pump light source for the two-dimensional material unit to pump the luminescent two-dimensional material to emit light. The photonic integrated device in the present disclosure can obtain different luminous bands by changing the number of layers or kinds of the luminescent two-dimensional material. Meanwhile, the photonic integrated device according to the present disclosure adopts an optical pumping luminescence method without forming a p-n junction, which simplifies process difficulty compared with an electrical pumping luminescence method of manufacturing the p-n junction based on the luminescent two-dimensional material in the prior art.
