We present the new function of tunable hollow waveguides with a variable air core. We exhibit a possibility of wide-angle beam steering from a tunable hollow waveguide and efficient tilt-coupling in a narrow air core hollow waveguide. Wide angle beam steering of over 40 degrees was demonstrated by calculation and preliminary experiment. In addition, a possibility of an efficient optical coupling with a narrow air core is discussed by the tilt-coupling scheme. The input and output coupling losses are 2.5 dB and 1 dB for 1 μm air core, respectively. Wide tunability in sub-wavelength air cores enables us to realize new functions of tunable hollow waveguides. |
