Problems solved by technology

3. Small quality
[0013] So far, no micro-nano fiber coil resonator combined with black phosphorus has been used for optical modulation, mainly because the traditional micro-nano fiber coil resonator has a fixed structure and is generally coated with a layer of low-refractive index polymer on the outside. However, when black phosphorus is coated on the inner wall of the micro-nano optical fiber coil resonator, due to the presence of low-refractive-index polymers, the evanescent field strength is relatively reduced, and the sensitivity is reduced accordingly.
If the exterior is not coated with a low-refractive-index polymer, its mechanical stability becomes poor and it is not easy to be used in practical applications

Embodiment 1

[0058] Preparation of black phosphorus deposited micro-nano optical fiber:

[0059] (1) Heat the ceramic microcouple heater to the operating temperature, which is about 1300 °C.

[0060] (2) Strip off the coating of a common single-mode optical fiber about 4 cm long, fix it on a micro-displacement platform (Newport, XML200), and place the stripped coating in the center of the ceramic microcouple heater.

[0061] (3) Start the LabVIEW program to control the movement of the micro-displacement platform to draw the fiber. By controlling the LabVIEW program, the fiber is tapered until the diameter of the cone waist is 2.35 μm.

[0062] (4) Remove the optical fiber, fix it on a clean low-refractive index plate that has been cleaned with alcohol, and use adhesive tape to fix the unstripped coating at both ends of the optical fiber.

Abstract

The invention discloses an optical modulator based on a coated black phosphorus micro-nano optical fiber roll type resonator, relates to the technical field of mid-infrared band lasers, and particularly discloses a manufacturing method of a coated black phosphorus micro-nano optical fiber. The method comprises the following steps: manufacturing a micro-nano optical fiber by using a fused biconicaltaper method; fixing the manufactured micro-nano optical fiber on a low refractive index plate; and coating the surface of the micro-nano optical fiber with black phosphorus by using a photodeposition method. The invention further discloses a manufacturing method of a roll-type resonator based on a coated black phosphorus micro-nano optical fiber and a control method for controlling the light modulation performance by changing the power of a tunable laser. Compared with a traditional micro-nano optical fiber structure, the black phosphorus-coated micro-nano optical fiber roll-type resonator prepared by the method is more stable in structure and higher in sensitivity, and the light modulation property is well improved.

Description

technical field [0001] The invention relates to the technical field of mid-infrared band lasers, in particular to an optical modulator based on a micro-nano optical fiber coil resonator coated with black phosphorus. Background technique [0002] At present, the human social environment continues to increase the demand for information technology to promote the rapid progress and development of human society. At present, people expect that the received information will not be limited by time and capacity conditions. Therefore, from the perspective of devices, the miniaturization, low power consumption and high speed of optical communication equipment have become the goals that scientific researchers have been working hard for. . At the same time, as a carrier of information, light has great advantages in terms of speed and anti-interference during transmission, but there is still a considerable gap compared with electronics in terms of device integration. However, the micro-...
