Optical Interference Coatings Design Contest 2007: triple bandpass filter and nonpolarizing beam splitter

Abstract

A triple bandpass filter (28 solutions received) and a nonpolarizing beam splitter (23 solutions received) were the subjects of the design contest held in conjunction with the 2007 Optical Interference Coatings topical meeting of the Optical Society of America. Fifteen designers participated using a wide spectrum of design approaches and optimization strategies to create the submissions. The results differ significantly, but all meet the contest requirements. Fabien Lemarchand wins both contests by submitting the thinnest (6254 nm) triple bandpass design and the widest (61.7 nm) nonpolarizing beam-splitter design. Michael Trubetskov is in second place, followed by Vladimir Pervak in both contests. The submitted designs are described and evaluated.

Design technique for all-dielectric non-polarizing beam splitter plate

“…(9) and Fig. 5 and 6] can be easily verified with any pro− fessional software specialized in optical coatings design, l the proposed non−polarizing beam splitter design is one of those with the fewest layers component (only 17), com− pared to the others also presented in the literature [9], l in addition to the fact that the optimized coating Eq. (9) (Figs.…”

Application of global optimization algorithms for optical thin film index determination from spectro-photometric analysis

“…[31]. Although one of the authors of this paper has achieved the best results in a thin film design contest with this method [32], there have been no other publications reporting the use of this approach for the thin film index determination.…”

Multi-wavelength metal-dielectric nonpolarizing beam splitters in the near-infrared range

“…This is because the effective indices of materials at oblique angles provide different functions of the angle of incidence for each polarized light, which limits the design of non-polarizing beam splitters (NPBSs). The nonpolarizing optical components were proposed and reported in the literatures [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

“…Shi and Wang [10] and Shi et al [11,12] investigated NPBSs with appropriate amplitude and phase. Recently, NPBSs submitted to the design contest held by 2007 Optical Interference Coatings conference were summarized and evaluated [13] and then Willey [14] interpreted nonpolarizing properties utilizing building-block patterns, which are theoretically and practically significant for the development of NPBSs. A non-polarizing filter was achieved based on the guidedmode resonance [15].…”

“…Limited attempts were made to study their differential phase [11][12][13]. In the present paper, a novel design of metal-dielectric NPBS with 21 layers is proposed to obtain the characteristics of 50% reflectance and 45% transmission for both polarization components and nearly-to-zero differential phases for 1310 and 1550 nm, the two wavelengths most widely used in the near-infrared range.…”
