[Show abstract][Hide abstract] ABSTRACT: Novel type of optical fiber sensor was proposed and demonstrated. The print-like fabrication technique fabricates multiple distributed feedback solid state dye lasers on a polymeric optical fiber (POF) with tapered coupling. This multi-active-sidecore structure was easily fabricated and provides multiple functions. Mounting the lasers on the same point of a multimode POF demonstrated a bending radius sensitivity of 20 m without any supports. Two axis directional sensing without cross talk was also confirmed. A more complicated mounting formation can demonstrate a twisted POF. The temperature property of the sensor was also studied, and elimination of the temperature influence was experimentally attained.
[Show abstract][Hide abstract] ABSTRACT: Bending and twisting sensors on optical fiber was demonstrated using waveguide dye laser mounted on the fiber. The lasing wavelength shift was observed via the fiber in which a pumping beam propagates.

[Show abstract][Hide abstract] ABSTRACT: Solid state DFB dye laser directly mounted on polymeric optical fiber. Multiple lasers can be pumped simultaneously and their output was coupled to the fiber. Bending sensor also proposed and two directional sensing was demonstrated.
[Show abstract][Hide abstract] ABSTRACT: The tunable waveguide dye laser on the plastic optical fiber (POF) was developed. Narrowband spectrum DFB laser operation of the dye laser pumped from optical coupling between optical fiber to the dye laser can be obtained, and wavelength modification with bending of the fiber can be observed.
