Article Synopsis
- A new tapered fiber bioprobe using Mach-Zehnder interference (MZI) is designed for sensitive optical sensing with a U-shaped structure for ease of use.
- The proposed sensor matches the sensitivity of traditional straight-tapered fiber sensors but offers benefits like flexibility, reduced liquid usage, and portability due to its insert-probe design.
- It has demonstrated effective immunoassays for human immunoglobulin G, featuring a low detection limit and potential applications in medical diagnostics and immunoassays.
We analyze a new type of photonic crystal fiber which consists of the core and cladding that distinct in topology by tuning the position of air holes in each hexagonal unit cell where the C symmetry is respected. The p-d band inversion between the core and cladding leads to topological interface modes inside the band gap, which can propagate along the fiber with a nonzero momentum in perpendicular to the corss section of a fiber. The helical topological interface modes possess the pseudospin-momentum locking effect inherited from the corresonding two-dimensional photonic crystal characterized by the Z topology.

This study demonstrates the ultrasensitive detection of complementary DNA (cDNA) by employing a nanointerface-sensitized fiber optic biosensor. The sensor consists of SMF-TNCF-MMF-SMF (abbreviated as STMS) structure with lateral offset.
