Abstract

Spatial confinement of paths in wireless optical communication enables bandwidth and resources reuse in adjacent environments. This property can also result in undesirable shadowing that occurs whenever an obstacle blocks signal paths between transceivers. Shadowing can result in service interruption and increased error rate. Spatial coding is possible to improve link performance and alleviate shadowing effect in wireless communication environment. In this paper, we propose an application of polymer holographic grating with the frustrated-total-internal-reflection (FTIR) structure to wavelength-band selection for optical wireless communication. A polymer holographic grating is fabricated by two beam interference at the wavelength of 532 nm. In the system, a multi-channel source is incident to the FTIR coupling structure which is made by a prism and polymer holographic gratings and acts as a wavelength-band selective filter. This scheme can be used in various systems which need flexible optical path and relative time delay according to each wavelength-band.
