Tunable attenuator based on polymer microstructured optical fibers
Optoelectronics Letters, 2007Based on polymer microstructured optical fibers (PMOF) and selective liquid crystal injection technology, a novel temperature control tunable attenuator is designed theoretically in this paper. In our experiments, PMMA microstructured optical fibers with high performance are drawn successfully and the selective injection of liquid crystal 5CB into ...

Direct Writing of Fiber Bragg Grating in Microstructured Polymer Optical Fiber
IEEE Photonics Technology Letters, 2012We report point-by-point laser direct writing of a 1520-nm fiber Bragg grating in a microstructured polymer optical fiber (mPOF). The mPOF is specially designed such that the microstructure does not obstruct the writing beam when properly aligned. A fourth-order grating is inscribed in the mPOF with only a 2.5-s writing time.

Optics Letters, 2009
Ultrahigh-resolution fiber-optic image guides--fused image fiber, faceplate, and taper--were fabricated by using microstructured polymer optical fiber (MPOF) preforms composed of two polymers: polymethylmethacrylate and polystyrene. The pixel diameter in the resultant MPOF-based image guides was as small as 3 microm.

Polymer optical microstructured fiber with birefringence induced by stress-applying elements
Optics Letters, 2014We report on the fabrication of a birefringent microstructured PMMA fiber with polystyrene stress-applying elements located in the solid part of the cladding. A microstructured part of the cladding composed of three rings of holes was made of a technical-grade PMMA by a drilling method.

High birefringent microstructured polymer optical fiber with frozen stresses
12th Conference on Integrated Optics: Sensors, Sensing Structures, and Methods, 2017We report on fabrication of a new type high birefringent microstructured polymer fiber with a PMMA stress applied element in the core. An inner part of preform consists regular three rings of holes, made by drilling method. Inside the microstructure we drilled an additional hole, where a special type – strongly stressed PMMA rod was placed.

Sensitivity of Birefringent Microstructured Polymer Optical Fiber to Hydrostatic Pressure
IEEE Photonics Technology Letters, 2013We present a PMMA birefringent fiber with enhanced polarimetric sensitivity to hydrostatic pressure, obtained by enlarging selected holes in the microstructured cladding. The fiber shows a linear response to pressure with small hysteresis in the pressure range up to 8.5 MPa and the sensitivity of 48 ${\rm rad}/{\rm MPa}\cdot{\rm m}$ at 600 nm.
