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...
