Abstract

Disclosed are an optical fiber coupling system and method. The system comprises an optical coupler (110), a first optical power detector (PD) (120), an input optical fiber (130) and a first adjustment platform (140); the optical coupler (110) is used to transmit incident light input via a first input port (111) to the input optical fiber (130) via an output port (113); the input optical fiber (130) is used to transmit the incident light to an input optical waveguide coupler, and transmit to the output port (113) reflected light reflected from the input optical waveguide coupler; the optical coupler (110) is also used to output the reflected light via the first input port (111) and a second input port (112); the first optical PD (120) is used to detect an optical power of the reflected light output via the second input port (112); and the first adjustment platform (140) is used to adjust the position of the input optical fiber (130) according to the optical power of the reflected light. An embodiment of the present invention improves an optical fiber coupling efficiency.

Description

technical field [0001] The present invention relates to the field of optical communications, and more particularly, to fiber-coupled systems and methods. Background technique [0002] Silicon photonics technology is currently a hot spot in the optical communication industry and academia. Almost all optical passive devices, such as modulators, filters, optical couplers, wavelength division multiplexers, and wavelength division multiplexers, can be realized by silicon photonics technology. Optical passive devices based on silicon photonics generally include an input optical waveguide coupler and an output optical waveguide coupler, which are used to guide the light in the optical fiber into and out of the optical passive device, respectively. Only when the light in the optical fiber is successfully coupled into the optical passive device, and then the light in the optical passive device is successfully coupled out, can the device be tested and its performance verified. There...
