DOI: 10.1117/1.oe.62.4.046101
Abstract: Abstract. By harnessing the heterogeneous combination of waveplates, we demonstrated a wavelength-tunable passband-squeezed polarization-diversified fiber loop (PDFL) comb filter. The PDFL comb filter is composed of a polarization beam splitter (PBS), two polarization-maintaining fiber (PMF)… read more here.
