Abstract

It is known that dispersive fiber has an ${\mathrm{LP}}_{01}$ mode cutoff wavelength that acts as a wavelength filter. With a dispersive polysiloxane polymer overlay on a side-polished single-mode fiber, an in-line tunable fiber short-pass filter with a tuning range of $\sim 400 \mathrm{nm}$ $\left(1250–1650 \mathrm{nm}\right)$ and a temperature variation of $15 {}^{°}\mathrm{C}$ was demonstrated. The rejection efficiency was greater than 50 dB, whereas the insertion and polarization-dependent losses were below 0.26 and 0.09 dB, respectively.
