a Design of fiber geometry structure for OCT imaging system working at 1310 nm. b Beam propagation simulation on a simplified forward-viewing fiber probe. The length of the SMF, the LDNCF, the cylindrical waveguide representing the microsphere, and the height of the axicon were set to 100 μm, 1234 μm, 425 μm, and 133 μm, respectively. The diameter of the SMF core, the LDNCF, the cylindrical waveguide, and the axicon bottom were set to 9 μm, 250 μm, 700 μm, and 700 μm, respectively
