Take the tube: Tubular structures can be fabricated by the cooperative self-assembly of the binary molecular components TPI and APO (see picture). This method can also be used to make a single binary tube capable of performing multiple photonic functions, such as an annular microcavity waveguide, waveguide modulation, and a controllable waveguide switch.
