Abstract
We demonstrate filtering characteristics of a polymer notch filter (PNF) with highly-ordered microphase-separated structure of block copolymers (BCPs). This PNF is characterized by an Optical Density > 5 blocking at the center wavelength and narrow blocking full bandwidth of 8 nm. Moreover, the wavelength is easily tuned by blending two BCPs with different molecular-weight. A low frequency Raman shift of 200 cm-1 are, in fact, detected with a sufficient resolution by using this filter in Raman spectroscopy.
