Abstract: An optical planar wavelength selective filter is formed on a printed circuit substrate. Low optical loss polymers are used to make a layered structure that contains waveguides and free travel zones. A diffraction grating is strategically placed on the printed circuit substrate so that light from one waveguide is diffracted by the grating to exit the free travel zone and pass through the other waveguides. The low optical loss polymer is a reaction product of the hydrolysis and polycondensation reaction of organically functionalized alkoxysilanes. With a proper grating, the apparatus can be used as an optical triplexer at frequencies of 1310, 1490, and 1550 nanometers.

Abstract: 1. A rotatable mirror optical switch arrangement (100) comprising: an input array of light sources (160); an output array of light receivers (180); a first rotatable platter (110) of mirror elements arranged between the input array and the output array whereby light (140, 150) from a desired one of the input array of light sources is reflected via the rotatable platter to a desired one of the output array of light receivers dependent on rotation of the first rotatable platter.
