Rn.To realize the continuous wavelength tunability of circular polarization inside a broad spectral variety more than 500 nm, the use of a wedge PCLC cell structure in addition to a continuous pitch formation within the wedge direction with the cell may be continuous Figure 2). As a A further principal benefit of this device is its one particular option (see wavelength vari essential and essential condition, the pitch Guretolimod Technical Information gradient of PCLCs must match the spiral pitch the wideband wavelength variety. thickness change in the wedge path from the PCLC cell [18]. modify determined by cell To understand Figurecontinuous wavelengthPCLC structure corresponding towards the excellent PCLC the two shows a schematic diagram on the tunability of circular polarization in wedge cell having a continuous pitch gradient. Cholesteric helical pitches are Combretastatin A-1 site quantized with spectral variety more than 500 nm, the use ofto satisfy the boundary condition on the wedge CLC cell the number of half-turns [13,19] a wedge PCLC cell structure along with a continuo with an alignment layer. Along the cell could be 1 in Figure 2), a linear formation inside the wedge direction from the wedge direction (+x-directionsolution (see Figure boost within the helical pitch (p) continuously occurred. Consequently, spatially, the wavelength essential and required in the PBG (no p pitch p) also continuously changed according to the sp position situation, the ne gradient of PCLCs will have to match the pitch by cell thickness transform inside the wedge path the PCLC adjust determinedchange along the wedge path around the PCLC cell. A technique to fabricateof the PCLC wedge cell structure having a pitch gradient more than 500 nm spectral variety is shown in Section three Figure two shows(Fabrication of PCLCdiagram with the PCLC structure corresponding to a schematic cells).tonic band is reflected at the R-PCLC cell, anddevice is its continuous wavelength variability within the s Yet another primary benefit of this then left-circularly polarized light inside the wideband wavelength cell, tonic band is reflected at the L-PCLCrange. in turn.PCLC wedge cell using a continuous pitch gradient. Cholesteric helical pitches a tized together with the number of half-turns [13,19] to satisfy the boundary condition of th CLC cell with an alignment layer. Along the wedge path (+x-direction in Fig linear raise inside the helical pitch (p) continuously occurred. Hence, spat wavelength position in the PBG ( ) also continuously changed ing for the pitch modify along the wedge path around the PCLC cell.

In our preceding study, in a vast wavelength selection of 500 an anti-reflective molecular concentration introducing a BK7 glass substrate coated with nm, a chiral layer (AR layer) on one particular side improved the refractive index mismatch the cell, air and glass layer in the CLC formed along the wedge path inbetween theas shown.
