example 1
[0026] Example 1: If image 3 As shown, the integrated interferometer described in the present invention can be a small sensor module, including a module package 301 , a light source 302 , a photoelectric detection and data processing chip 303 and a single optical fiber 304 . The sensing portion 305 of the single optical fiber 304 is in the test area outside the sensor module package 301 . The module can be used for precise measurement and real-time monitoring of various physical quantities such as temperature, pressure, and magnetism, and can be widely used as a sensor node in sensor networks and Internet of Things systems.
[0027] The detection results of the sensor module can be read out by an external system through a line connection, such as Figure 4 As shown, the interferometer sensor module 401 is on an electronic circuit board 402, and the circuit connection 403 at one end of the electronic circuit board 402 includes the power supply circuit of the electronic circui...

[0029] Example 2: Combining with Figure 6 , an example when the present invention is used as a magnetic sensor module will be described in detail below. It consists of a light source 601, a single-mode single-core input fiber 602, a first splitter tapered coupling region 603, a single-mode dual-core sensing fiber 604, a light-combining tapered coupling region 605, a single-mode single-core transmission fiber 606, a second splitter It consists of a tapered coupling region 607 , a single-mode dual-core output optical fiber 608 , and a photoelectric detection chip 609 . The photodetection chip 609 is composed of two identical on-chip photodiodes 691, 692, an on-chip differential signal amplifier 693, an analog-to-digital converter (ADC) circuit 694, an on-chip memory 695, and an interface circuit 696.
[0030] The pulsed optical signal emitted by the light source 601 is sent into the single-mode dual-core sensing optical fiber 604 through the single-mode single-core input fiber...
