Abstract

The invention provides a black phosphorus optical modulator, including a black phosphorus optical modulator body, a groove-type slide and a coverslip. The groove-type slide comprises a groove. The black phosphorus optical modulator body is held in the groove. The coverslip covers the groove-type slide to seal the groove. The black phosphorus optical modulator provides a stable storage environment for black phosphorus, and a problem that black phosphorus is easy to oxidize is effectively solved. The structure of the black phosphorus optical modulator is different from structure of a conventional ridge waveguide, and size of the optical modulator is reduced, and volume of the optical modulator is reduced. The invention also provides a manufacturing method for the black phosphorus optical modulator. The method comprises: providing a groove-type slide and a black phosphorus optical modulator body, the groove-type slide including a groove and an upper surface abutting the groove, putting the black phosphorus optical modulator body in the groove; providing a coverslip, coating a shadowless glue on the upper surface of the surface of the coverslip, covering the coverslip on the upper surface to seal the groove, and after curing, the black phosphorus optical modulator is obtained.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a black phosphorescent modulator and a preparation method thereof. Background technique [0002] Optical modulator is one of the most important devices in modern optoelectronic communication system, which can realize fast and accurate coding and modulation of signals. The basic structure of an optical modulator includes an optical waveguide in which an electric field is applied. When light passes through the optical waveguide structure, the refractive index or absorptivity of the incident light will change, thereby causing changes in the phase or amplitude of the output light. Exploring high-speed, broadband and small-sized optical modulators is one of the hot topics in this research field. [0003] Black phosphorus is located at the 15th position in the periodic table of elements, and the symbol of the element is P, which is a black crystal with metallic luster. In 2014, b...
