This invention belongs to the field of fiber optic sensing technology, and discloses an integrated fiber optic sensor for seawater temperature, salinity, and depth based on a composite microstructure and its fabrication method. A single-mode fiber, a first coreless fiber, and a graded-index fiber are sequentially fused together to form a collimation structure for long-distance beam transmission. One end of the graded-index fiber is sequentially connected to a hollow-core fiber and a second coreless fiber. The core of the hollow-core fiber is filled with polydimethylsiloxane, located at the intersection of the cores of the graded-index fiber and the hollow-core fiber. The microsphere structure is divided into a cladding cavity and an air cavity from the outside to the inside. One end face of the second coreless fiber intersects with the air cavity and cladding cavity of the microsphere structure. Test results show that the integrated fiber optic sensor for seawater temperature, salinity, and depth based on the composite microstructure has the potential for integrated measurement of seawater temperature, salinity, and depth parameters.

This application relates to the field of radio frequency microwave circuit technology and discloses a hybrid integrated millimeter-wave coaxial radial triode, including a first coaxial line, a dielectric substrate, three output circuits disposed on the dielectric substrate, and a second coaxial line. The output circuit includes a coaxial probe, an arcuate stripline, and a width-change-abrupt stripline connected in sequence, with at least one slot structure disposed on the arcuate stripline. This application utilizes a concentric arcuate stripline disposed inside the first coaxial line solely for transmitting excitation signals, and employs a circuit design on the arcuate stripline that enables the implementation of a bandpass filter structure. This allows the signal excited and coupled by the coaxial probe to be transmitted via the arcuate stripline to three signals of different specific frequency bands to a standard microstrip line connected outside the first coaxial line. This effectively improves upon the problem of the difficulty and large workload in designing common port impedance matching networks in traditional circuit structures.
