In this paper the results of calculations and optimization of parameters of concave holographic diffraction grating for use in WDM multi/demultiplexer for data transmission systems with polymer optical fibers are presented.
High speed vertical-cavity-surface-emitting lasers (VCSELs) are attractive candidates for use in future wavelength division multiplexed passive optical network (WDM-PON). In this paper we describe a proof-of principle implementation of such a remodulation scheme with a directly modulated VCSEL array. Although a discrete receiver, VCSEL array and wavelength filters were used here for implementing the...
We designed an innovative frequency multiplexer based on contra-directional coupling and standing-wave resonators within a photonic crystal (PhC) structure. Three add-drop filters were cascaded, and the lattice periods of the PhC strips containing the cavities were changed to tune the dropped frequencies, with a very high degree of freedom. Each filter has a 1 nm bandwidth around 1550 nm and the three...
