Abstract

The invention relates to the field of optical loss testing, and discloses an optical device, and an optical chip loss testing device and method. The system comprises a micro-ring resonance system, aninput system and an output system, the input system comprises a first optical fiber and a first optical coupler, the output system comprises a second optical fiber, a second optical coupler and a third optical coupler, one end of the first optical coupler is connected with the first optical fiber, and the other end of the first optical coupler is connected with the micro-ring resonance system; thesecond optical coupler is arranged at the uplink end of the micro-ring resonance system, one end of the second optical coupler is connected with a second optical fiber, and the other end of the second optical coupler is connected with the micro-ring resonance system; and the third optical coupler is arranged at the downlink end of the micro-ring resonance system, one end of the third optical coupler is connected with the second optical fiber, and the other end of the third optical coupler is connected with the micro-ring resonance system. The tested optical device and the optical chip are nested into the micro-ring resonance system, so that the test accuracy, stability and flexibility are improved.

Description

technical field [0001] The invention relates to the field of optical loss testing, and more specifically relates to an optical device and an optical chip loss testing device and method. Background technique [0002] Optical loss is an important parameter index to measure the performance of optical devices and optical chips, and determines the application scenarios of optical devices and optical chips. Typical optical test setups require perfect alignment of the fiber and optical coupler, requiring the fiber to be at the same physical location for each test. Optical components such as optical fibers, optical couplers, and optical waveguides in test devices on the market have a certain impact on test results, and cannot accurately calibrate the optical loss of the optical device and optical chip under test. Therefore, it is urgent to invent a test with high precision. , high stability and high flexibility test device. Contents of the invention [0003] In view of this, the...
