“…The MZIs also enable demultiplexing and deinterleaving. These devices have much better crosstalk immunity performance than sinusoidal Mach-Zehnder interleavers and demultiplexers, 12 but not as good as in flattop and as broad in passband as asymmetric Mach-Zehnder interleavers and demultiplexers. 1,7 These devices can be conveniently implemented using the silicon or InP integrated optic technologies.…”

Novel demultiplexer configurations based on concatenated Mach-Zehnders and a ring resonator are presented. These new devices exhibit high channel isolation, flexibility, no loss, and megahertzadjustable full width at half maximum (FWHM) suitable for narrow channel spacing. General design equations are described. Examples of a 1 ϫ4-2.5-GHz demultiplexer and a 2.5-GHz/5-GHz interleaver are reported. These designs have channel isolation Ͼ40 dB, 128 MHz FWHM, 10 dB gain. These devices can be conveniently implemented using the silicon or InP integrated optic technologies. A fabrication tolerance analysis is carried out. The worst figures for the previous designs are 220 MHz FWHM, 23-dB channel isolation, and 5.7-dB gain and can be readjusted with a gain control.

“…Several technologies are used to carry out wavelength separation for demultiplexing a composite signal. Very common technologies are thin film filters, arrayed waveguide grating (AWG) [4], fiber Bragg grating (FBG), free space diffraction grating [5][6][7]. FBGs based on diffraction have been used to constitute multichannel Mux/DeMux devices, in which all discrete filters must be cascaded in a serial manner.…”

“…To investigate the possible use of DPMG, the volume grating in optical interconnect is replaced by Dynamic Phase Modulated Grating. To analyze the variation of polarization dependence loss with recording angle, Equa-tions(3) and(4) are modified in accordance with Equation(5).Polarization dependence loss for such DPMG for P and S polarization can be found as…”

We in this paper propose a model to increase the diffraction efficiency of a holographic grating at 1550 nm for multiplexing application. To use such a grating, polarization dependence loss is introduced analytically and then optimized for its minimum value A configuration of holographic grating is proposed based on both maximum diffraction efficiency and minimum polarization dependence loss. The proposed grating is expected to find importance in optoelectronic multichip module
